[PATCH] nouveau: synchronize "scratch runout" destruction with the command stream
When nvc0_push_vbo calls nouveau_scratch_done it does not mean
scratch buffers can be freed immediately. It means "when hardware
advances to this place in the command stream the scratch buffers
can be freed".
The bug existed for a very long time. Nobody noticed, because
"scratch runout" code path is rarely executed.
