radeonsi: Don't use compute queue with regalloc hang bug

Browse Source 
It already didn't use compute queues on GFX6, but some GFX7
chips are also affected by the same bug.

Compute queues may run compute dispatches in parallel with
the graphics queue, even from other processes/apps.
At the moment we don't have a way to restrict all workgroups
to 256 invocations, so instead let's make sure not to use the
compute queue.
