nvme: introduce a nvme_host_path_error helper

Browse source

When using nvme native multipathing, if a path related error occurs
during ->queue_rq, the request needs to be completed with
NVME_SC_HOST_PATH_ERROR so that the request can be failed over.

Introduce a helper to complete the command from ->queue_rq in a wait
that invokes nvme_complete_rq.
