radv: force cs/ps/l2 flush at end of command stream. (v2)
This seems like a workaround, but we don't see the bug on CIK/VI.
On SI with the dEQP-VK.memory.pipeline_barrier.host_read_transfer_dst.*
tests, when one tests complete, the first flush at the start of the next
test causes a VM fault as we've destroyed the VM, but we end up flushing
the compute shader then, and it must still be in the process of doing
something.
Could also be a kernel difference between SI and CIK.
v2: hit this with a bigger hammer. This fixes a bunch of hangs
in the vk cts with the robustness tests.
