radv: don't skip PS/VS partial flush

This patch helps lower high priority compute latency. Found by
bisecting a perf regression on computeparticles with high priority
compute queues enabled.

Reverting this micro-optimization doesn't seem to have any negative
effect on performance on Dota2 or ssao.
