I'd suggest to simply store the complete virtio_gpu_object_params struct
in virtio_gpu_object instead of re-creating it here.

Put them into a new block separated by newline, add a comment saying
those are needed for virtio_gpu_deferred_create?

Additionally check for param->dumb to take the deferred code path? That
should make sure there is no fence.
take care,
