gallium/radeon: fix performance of buffer readbacks

We want cached GTT for all non-persistent read mappings.
Set level = 0 on purpose.

Use dma_copy, because resource_copy_region causes a failure in the PBO
read of piglit/getteximage-luminance.

If Rocket League used the READ flag, it should get cached GTT.

v2: mask out UNSYNCHRONIZED
