scsi: lpfc: SLI path split: Refactor VMID paths

This patch refactors the VMID paths to use SLI-4 as the primary interface:

 - Conversion away from using SLI-3 iocb structures to set/access fields in
   common routines. Use the new generic get/set routines that were added.
   This move changes code from indirect structure references to using local
   variables with the generic routines.

 - Refactor routines when setting non-generic fields, to have both SLI3 and
   SLI4 specific sections. This replaces the set-as-SLI3 then translate to
   SLI4 behavior of the past.
