drm/xe/vf: Reset TLB invalidations during VF post migration recovery

Browse source

TLB invalidations requests can be lost during VF post-migration
recovery. Since the VF has migrated, these invalidations are no longer
needed.

Reset the TLB invalidation frontend, which will signal all pending
fences.

v3:
 - Move TLB invalidation reset after pausing submission (Tomasz)
 - Adjust commit message (Michal)
