scsi: ibmvfc: Add FC payload retrieval routines for versioned vfcFrames
The FC iu and response payloads are located at different offsets depending
on the ibmvfc_cmd version. This is a result of the version 2 vfcFrame
definition adding an extra 64bytes of reserved space to the structure prior
to the payloads.
Add helper routines to determine the current vfcFrame version and return a
pointer to the proper iu or response structure within that ibmvfc_cmd.
