r600g/radeonsi: Map transfer staging texture unsynchronized when possible
The transfer staging texture is always freshly allocated, so for write-only transfers we don't need to explicitly wait for the BO to become idle. Squeezes a few hundered MB/s more out of x11perf -shmput500 with glamor. Reviewed-by: Marek Olšák <[email protected]>
