Gerd Hoffmann 979f0b2f77 virtio-gpu: fix resource leak in virgl_cmd_resource_unref ...

When the guest sends VIRTIO_GPU_CMD_RESOURCE_UNREF without detaching the
backing storage beforehand (VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING)
we'll leak memory.

This patch fixes it for 3d mode, simliar to the 2d mode fix in commit
"b8e2392 virtio-gpu: call cleanup mapping function in resource destroy".
