scsi: ibmvfc: implement nvme-fc FCP abort callback

Browse source

Implement the NVMe-FC FCP abort callback by issuing an NVMF cancel MAD
on the same submission queue used by the original FCP request.

Use the original request event stored in abort_req->private to recover
the associated ibmvfc queue, then allocate a new event from that queue
so the cancel is sent on the matching nvme_scrq. Factor the TMF setup
into a dedicated helper, mirroring the LS abort path, and populate the
cancel key, task tag, target WWPN, and association ID needed for the
VIOS NVMF abort request.

The abort path sends the cancel synchronously, waits for completion,
frees the temporary event, and logs non-zero MAD status values for
debugging.
