Revert "sna: Close each client op with an arbitrartion check"
This reverts commit b5ac286c9bb0 as it escaped before being completed.
It proved it's worth in preventing sna from hogging the GPU for too long
under x11perf stress, but it didn't check to see if there was enough
space left in the batch before emitting the dword. Simply revert the
patch for now.
