virtio_gpu_have_udmabuf() emits a warning if udmabuf is not available,
which is spurious when using Rutabaga.
I think virtio_gpu_have_udmabuf() should be renamed to
virtio_gpu_init_udmabuf() or something, let it set errp instead of
emitting a warning, and call it only when Rutabaga is not in use. That
clarifies the timing when an error message will be shown.
