From SAM-4, section 5.13 (Sense Data);
“When a command terminates with a CHECK CONDITION status, sense data shall be returned
in the same I_T_L_Q nexus transaction (see 3.1.50) as the CHECK CONDITION status. After
the sense data is returned, it shall be cleared except when it is associated with a unit
attention condition and the UA_INTLCK_CTRL field in the Control mode page (see SPC-4)
contains 10b or 11b.”
SPDK does not set UA_INTLCK_CTRL to 10b or 11b, so we set the unit attention condition
immediately against a single IO or Admin IO after reporting it via a CHECK CONDITION.
Once the failed IO received at iSCSI initiator side, it will be retried. In the case of
resize operation, if there is no IO from iSCSI initiator side, the unit attention
condition will be delayed to report until the first IO is received at the iSCSI target
side.
Meanwhile, we clear the resizing (newly added) flag on our SCSI LUN structure after
first time we report the resize unit attention condition.
The kernel initiator won’t actually resize the corresponding block device automatically.
It will report a uevent, and then you can set up udev rules to trigger a rescan. SPDK
iSCSI initiator will automatically report the LUN size change.

Previously we mixed SQ/CQ definition together, one queue pair

while here, we split the queue pair definition into SQ and CQ
respectively as code cleanup.
The NVMf library uses queue pair concept, but for vfio-user
case, each SQ created by VM is mapped to NVMf queue pair, so
we also change `connected_qps` to `connected_sqs` to reflect
the fact.
No actual code logic change in this commit.

More precise stubs for spdk_nvme_poll_group are critically important
to verify upcoming changes.
Add a flag is_failed to struct spdk_nvme_qpair separately from
is_connected. This is used to inject error to a connection.
Replace a single list qpairs by two lists, connected_qpairs and
disconnected_qpairs for struct spdk_nvme_poll_group.
Then utilize these to manage qpair in poll group.
spdk_nvme_ctrlr_reconnect_io_qpair() is not used in the NVMe bdev
module now. Remove the corresponding stub.
Adjust polling count accordingly.

Previously, when connecting qpair, we allocated stats per qpair if poll
group is not used or we set stats per poll group otherwise.
Then when deleting qpair, we freed per qpair stats if allocated.
However, if qpair is still not completely disconnected after removing
qpair from poll group, pqpair->stat is use-after-free and it causes
a segmentation fault.
To fix this issue, we set pqpair->stat to &g_dummy_stats instead.

nvme_ctrlr_disconnect_qpair() calls nvme_poll_group_disconnect_qpair() if the qpair
uses a poll group, and nvme_poll_group_disconnect_qpair() calls
nvme_ctrlr_disconnect_qpair() if the state of the qpair is not DISCONNECTING.
This relationship made the code very complex.
A few patches starting from this patch simplifies disconnect and free qpair
operations.
This patch swaps the ordering of nvme_ctrlr_disconnect_qpair() and
spdk_nvme_poll_group_remove() in spdk_nvme_ctrlr_free_io_qpair().
This ensures the qpair is disconnected when spdk_nvme_ctrlr_free_io_qpair()
calls spdk_nvme_poll_group_remove().
This enables us to limit spdk_nvme_poll_group_remove() to be available
only for disconnected qpairs.

For the purpose to support shared IO CQ feature, we will construct
the queue pair data structure at the beginning, and setup SQ/CQ
separately in CREATE IO SQ/CQ routine.
Previously we will disconnect queue pair when got a DELETE IO CQ
command, now we disconnect queue pair when got a DELETE IO SQ command,
and in the disconnect completion callback, we will release the IO SQ
resources, there is a case that the VM will just RESET/SHUTDOWN
controller when IO queue pairs are connected, for this case, we
will also try to release CQ resources in the disconnect completion
callback.
`free_qp` function now is only called when destroying a controller.
