drm/virtio: track created object state
Track whenever the virtio_gpu_object is already created (i.e. host knows
about it) in a new variable. Add checks to virtio_gpu_object_attach()
to do nothing on objects not created yet.
Make virtio_gpu_ttm_bo_destroy() use the new variable too, instead of
expecting hw_res_handle indicating the object state.
