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.
