Tried that branch.

No timeouts. Yay!
But it seems crtcs can be (temporarely) disabled now, so we might have to pick up the crtc from old_state in virtio_gpu_plane_atomic_update to figure which virtual output needs to be turned off. Ran into this last week already. Happened with multihead setups only, but the same patch fixes this one too ;)
