Work with nvme native multipath, if a path related error occurs when
queue_rq call HBA drive to send request, queue_rq will return
BLK_STS_IOERR to blk-mq. The request is completed with BLK_STS_IOERR
instead of fail over to retry.
queue_rq need call nvme_complete_rq to complete the request with
NVME_SC_HOST_PATH_ERROR, the request will fail over to retry if needed.
