Add blk_mq_set_request_complete and nvme_complete_failed_req for two bug
fixs.
First avoid double request completion for nvmf_fail_nonready_command.
Second avoid IO error for nvme native multipath.

V4:
	- add status parameter for nvme_complete_failed_req.
	- export nvme_complete_failed_req instead of inline function.
V3:
	- complete the request just for HBA driver path related error.
V2:
	- use "switch" instead "if" to check return status.

Chao Leng (5):
  blk-mq: introduce blk_mq_set_request_complete
  nvme-core: introduce complete failed request
  nvme-fabrics: avoid double request completion for
    nvmf_fail_nonready_command
  nvme-rdma: avoid IO error for nvme native multipath
  nvme-fc: avoid IO error for nvme native multipath
