radv: do not invalidate the L2 metadata cache on compute queues

Browse Source 
The flush VA space was only allocated for command buffers on the
graphics queue. Also, the ZPASS_DONE event should never be emitted
on compute queues because it hangs.

Invalidating the L2 metadata cache is only required for coherency
between the RBs and L2, so only on the graphics queue.

The L2 cache is invalidated at beginning of any IBs and that should
also invalidate the L2 metadata cache for compute anyways.

Fixes: 4a783a3c ("radv: Use L2 coherency on GFX9+.")
