drm/xe/tlb: ensure we access seqno_recv once

Browse source

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.
