[RFC v2 06/18] lpfc: vmid: Supplementary data structures for vmid

From: Gaurav Srivastava <gaurav.srivastava at broadcom.com>
This patch adds additional data structures for supporting the two
versions of vmid implementation. First type uses app header while the
other types uses priority tagging mechanism. These data structures
are used mostly for ELS and CT commands for the two vmid implementation.
