scsi: lpfc: Move determination of vmid_flag after VMID reinitialization completes

If priority tagging is set in the service parameters of a FLOGI cmpl, then
we update the vmid_flag. In the current logic, if a follow up FLOGI cmpl
updates its service parameters such that priority tagging is no longer set,
then the vmid_flag ends up keeping stale data.

Fix by ensuring we clear the vmid_flag member during lpfc_reinit_vmid, and
check the priority tagging service parameter after reinitialization of the
vmid data structures.
