Ensure we load gt->tlb_invalidation.seqno_recv once, and use that for our seqno checking. The gt->tlb_invalidation_seqno_past is a shared global variable and can potentially change at any point here. However the checks here need to operate on a stable version of seqno_recv for this to make any sense.
