When a request is queued failed, if the fail status is not
BLK_STS_RESOURCE, BLK_STS_DEV_RESOURCE, BLK_STS_ZONE_RESOURCE,
the request is need to complete with nvme_complete_rq in queue_rq.
So introduce nvme_try_complete_failed_req.
The request is needed to complete with NVME_SC_HOST_PATH_ERROR in
nvmf_fail_nonready_command and queue_rq.
So introduce nvme_complete_failed_req.
For details, see the subsequent patches.
