virtio-gpu: clear command and fence queues on reset
It was never correct to not clear them. Due to commit "3912e66a3feb
virtio-vga: fix reset." this became more obvious though. The virtio
rings get properly reset now, and trying to process the stale commands
will trigger an assert in the virtio core.
