nvmet: implement valid sqhd values in completions
To support sqhd, for initiators that are following the spec and paying attention to sqhd vs their sqtail values: - add sqhd to struct nvmet_sq - initialize sqhd to 0 in nvmet_sq_setup - rather than propagate the 0's-based qsize value from the connect message which requires a +1 in every sqhd update, and as nothing else references it, convert to 1's-based value in nvmt_sq/cq_setup() calls. - validate connect message sqsize being non-zero per spec. - updated assign sqhd for every completion that goes back. Also remove handling the NULL sq case in __nvmet_req_complete, as it can't happen with the current code.
