When nvmet_req_init() fails, __nvmet_req_complete() is called
to handle the target request via .queue_response(), so
nvme_loop_queue_response() shouldn't be called again for
handling the failure.
This patch fixes this case by the following way:
- move blk_mq_start_request() before nvmet_req_init(), so
nvme_loop_queue_response() may work well to complete this
host request
- don't call nvme_cleanup_cmd() which is done in nvme_loop_complete_rq()
- don't call nvme_loop_queue_response() which is done via
.queue_response()
