scsi: ibmvfc: implement nvme-fc IO command submission callback

Browse source

Add helpers to initialize an ibmvfc command from an nvmefc_fcp_req,
map request scatterlists into either an inline descriptor or an external
DMA pool list, and submit the request on the selected NVMe hardware
queue. On completion, translate ibmvfc status into the NVMe-FC response
format, including transferred length and CQE handling for no-DMA
responses.

Also store the NVMe request pointer in struct ibmvfc_event so the
completion path can finish the original request.
