[RFC 13/16] lpfc: vmid: Appends the vmid in the wqe before sending request

[Muneendra <muneendra.kumar@broadcom.com>]

From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>

This patch adds the vmid in wqe before sending out the request.
The type of vmid depends on the configured type and is checked before
being appended.
