Upcoming patches will support DIF insert and strip feature in
iSCSI target and the feature will be implemented by utilizing
iovecs.
Even when we support the DIF feature, we want to keep current
batched PDU flush, and current requirement that there must be
enough free iovecs to map all segments of a PDU is too strict.
This patch alleviates the requirement by passing remaining
number of iovecs to spdk_iscsi_build_iovs().

Building iovecs had been done in spdk_iscsi_build_iovs() and
fast-forwarding iovecs for the partially written first PDU had
been done in-line separately.
This patch unifies these two operations into spdk_iscsi_build_iovs().
Fast-forwarding iovecs is necessary only for the first PDU, but the
operation is applied to all PDUs after this patch.
Extra overhead will be negligible because usually at most two
iovecs are consumed, one is for the base header segment and another
is for the data segment.

When the specified buffer size to spdk_bdev_io_get_buf() is greater
than the permitted maximum, spdk_bdev_io_get_buf() asserts simply and
doesn't call the specified callback function.
SPDK SCSI library doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
Bdev perf tool also doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
When we support DIF insert and strip in iSCSI target, the read
buffer size iSCSI initiator requests and the read buffer size iSCSI target
requests will become different.
Even after that, iSCSI initiator and iSCSI target will negotiate correctly
not to cause buffer overflow in spdk_bdev_io_get_buf(), but if iSCSI
initiator ignores the result of negotiation, iSCSI initiator can request
read buffer size larger than the permitted maximum, and can cause
failure in iSCSI target. This is very flagile and should be avoided.
This patch do the following
- Add the completion status of spdk_bdev_io_get_buf() to
spdk_bdev_io_get_buf_cb(),
- spdk_bdev_io_get_buf() calls spdk_bdev_io_get_buf_cb() by setting
success to false, and return.
- spdk_bdev_io_get_buf_cb() in each bdev module calls assert if success
is false.
Subsequent patches will process the case that success is false
in spdk_bdev_io_get_buf_cb().

The example would endlessly loop in unregister_dev()->spdk_nvme_
ctrlr_free_io_qpair(), if the device has been removed after leave
hotplug monitoring. Add the timeout callback to handle this corner
case. The case will not be friendly to newcomers, if we use the event
framework to update it, because the hotplug has been hidden in frame
work.

Removing band from "free list" is moved from FTL_BAND_STATE_OPENING
to FTL_BAND_STATE_PREP state's change actions.
This will fix race condition when one band is prepared (erased)
and write pointer is trying to get next active band.

ENOMEM is expected when nvme_qpair will be out of resources.
In such a case ENOMEM shall be propagated to allow upper (bdev)
layer proper handling.

When an operation fails, we shouldn't pass a handle or
a 'valid' blob ID to the caller's completion function.
The caller *should* ignore it when bserrno != 0, but
it's best to not take that chance.
Fixes#685.
Note: #685 seems to have a broader issue related to
a possibly locked NVMe SSD in the submitter's system.
This only fixes the assert() that was hit.

This utility used to be called "bdevtest" so that's
what opts.name was set to for spdk_app_opts_init().
Change it to the new name "bdevio".
