d969ac445a io_channel: Remove per-channel priority
This wasn't used anywhere and we currently believe there
are superior software-only techniques for controlling
quality of service.

2e28ef9d02 scsi: fix scsi compliance issue for inquiry VPD NAA identifier
NAA locally assinged designator(3h) format was defined in SPC4,
as SPDK claimed can only support SPC3, so we used NAA IEEE
extended identifier format instead.

2e3f07ac40 bdev: add spdk_io_channel parameter to spdk_bdev_reset
This ensures that all spdk_bdev_io structures now have
an attached channel, simplifying some future work around
things like counting the number of outstanding IOs for
a given channel (which otherwise would have had to
account specially for resets).

Reset semantics are still that they affect the entire bdev
and not just the channel it was submitted on.

b9bcc3531e bdev: make enum spdk_bdev_io_status private
The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired
format regardless of what kind of error is stored inside the bdev_io.

Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.

de5ffac4ec scsi: factor out read/write LBA range check
The SCSI read and write functions use the same LBA range check, so move
it up to spdk_bdev_scsi_readwrite().

spdk_bdev_scsi_read() previously passed task->transfer_len / blen rather
than xfer_len to the LBA range checking function, but this should
actually be using the transfer length field from the CDB (which is the
xfer_len parameter).

91b13bd105 scsi: don't change bdev_io status in spdk_scsi_task_put()
The SCSI task bdev I/O should never be pending when spdk_scsi_task_put()
is called, and just setting the status to failed is not correct (when
the bdev eventually completes the I/O, it will write into the now-freed
bdev_io, which may be reused by someone else).
