scsi: lpfc: Reduce pointer chasing when accessing vmid_flag

For all FLOGI completions, the vport->phba->pport pointer is actually a
pointer to the original vport pointer because FLOGIs always complete on
the physical lpfc_vport object.  Thus, we can reduce the
vport->phba->pport->vmid_flag dereference to simply vport->vmid_flag.
