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.
