anv: Do an end-of-pipe sync before updating AUX table entries

Browse Source 
We've found in GL that an actual end-of-pipe sync is required before
invalidating the aux tables and that a simple CS stall is insufficient.
If we're about to modify the actual AUX table entries from the GPU, we
should definitely make sure it's stopped dead before we do so.
