scsi: ibmvfc: implement LLDD callbacks for mapping nvme-fc queues

Browse source

Implement the NVMe-FC queue create and delete callbacks and map NVMe
controller queues onto ibmvfc hardware queues.

Use qidx of NVMe controller queue to map onto a ibmvfc_queue channel.
The Admin queue is always qidx 0 and general practice among other
drivers is to map both the Admin queue and first IO queue to the same HW
queue. Add a new ibmvfc_nvme_qhandle struct that will be used as the
opaque queue handle by the NVMe-FC layer when issuing fcp IO.
