7d87273f60 nvmf: Reimplement abort handling
Now that the qpairs are stored on the poll groups,
reimplement abort handling to search each one. This
doesn't add new functionality compared to before - it
still only aborts AER commands.

eb387189c2 nvmf: don't change NN while ctrlrs exist
This was partially fixed in commit 1e481d0438e6 ("nvmf: Do not allow NN
to change while connections present"), but we did not handle the case
where the user asked to add a NS with a NSID outside the current NN.

This patch reworks the logic (again) to be more straightforward and
hopefully more obviously correct.

Some confusion between max_allowed_nsid and max_nsid is also clarified;
if max_allowed_nsid is set, then max_nsid == max_allowed_nsid at all
times, so we don't need the extra logic when calculating NN in
spdk_nvmf_ctrlr_identify_ctrlr().

b95fc6fc64 nvmf: Return the correct error for out-of-range QID
This one is actually a bit tough to deduce in the specification.
The NVMe-oF spec says that QID errors detected in the RDMA
transport shall return an RDMA-specific error indicating
the problem. However, our code doesn't detect the error in
RDMA-specific code, and it isn't clear if the language is
a "must" or a "should".

The NVMe specification does clearly indicate what error
to return on invalid QID in response to a Create
I/O Queue Pair command. For now, return that while
we game plan whether we need to call into the RDMA
transport to correctly report this error.

b6f90c527a nvmf/rdma: monitor asynchronous events
NVMf cnx acceptor poller is changed to check the asynchronous events
from the RDMA devices.

RDMA async events are polled together with RDMA CM events; the file
descriptors are combined into a poll fd array and processed in a single
poll syscall.

The errors handler is an empty placeholder for this patch, it just
prints the kind of event read from the IB device context.
The work for implementing event handling is left for later.

cbbec6dd16 nvmf: make each io qpair recycled by its own thread
This patch selects part of commit:
adfa9f6dc75d4c541beeb3269442552f7cbf5d7a

In the previous patch, the failed reason is the logic
that admin qpair actively destroys the ioqpair when
the admin qpair is recevied early. For this part,
we need to investigate it later since for multiple core
usage in our current handling case, we possibly have
admin qpair firstly to enter the destruct phase even if
the initiator sends the I/O qpair deletion first. Thus,
the ioqpair deletion can be recycled twice.

And this patch is selecting the part of the logic:
only to make each ioqpair recycled by its own thread.

Performing a subsystem update on each poll group after the addition or
removal of a namespace allows us to avoid the case where we pause a
subsystem, perform a removal, then an addition, resume the subsystem and
don't update the channel for that subsystem. This, however requires that
spdk_nvmf_subsystem_remove_ns be asynchronous.

27d47b9a10 nvmf: make the qpair disconnnect in the right order.
Reason: Initiator sends the qpair deletion in wrong order.
The correct order should be all io qpairs deletion and then
the admin qpair deletion. However, nvme perf does not follow
this since we did not catch ctrlr + c. If we catch ctrlr + c,
we need to use the spdk app framework, or other methods. We should
support this in another patch.

Morever, to prevent the incorrect behavior causing the coredump
of target, we need also consider such case in our NVMe-oF target
design. And this patch, can solve this issue, it will defer the
admin qpair deletion when there are still active io qpairs.
