scsi: ibmvfc: Use correlation token to tag commands

The vfcFrame correlation field is a 64bit handle that is intended to trace
I/O operations through both the client stack and VIOS stack when the
underlying physical FC adapter supports tagging.

Tag vfcFrames with the associated ibmvfc_event pointer handle.
