drm/xe/gt: tweak placement for signalling TLB fences after GT reset

Browse Source 
Assumption here is that submission is disabled along with CT, and full
GT reset will also nuke TLBs, so should be safe to signal all in-flight
TLB fences, but only after the actual reset so move the placement
slightly.
