A request will be cancelled when a queue is deleted, so we should
be returning a status of NVME_SC_ABORT_QUEUE.

Use NVME_SC_ABORT_QUEUE instead of NVME_SC_HOST_ABORTED_CMD is not a 
good idea.
NVME_SC_HOST_ABORTED_CMD is a host path related error, Now used to check 
if need fail over retry by multipath.
You are correct; this patch will be dropped for the next iteration.

Cheers,
