drm/xe: Don't support execlists in xe_gt_tlb_invalidation layer
The xe_gt_tlb_invalidation layer implements TLB invalidations for a GuC
backend. Simply return if in execlists mode. A follow up may properly
implement the xe_gt_tlb_invalidation layer for both GuC and execlists.
Fixes: a9351846d945 ("drm/xe: Break of TLB invalidation into its own file")
