drm/virtio: pass virtio_gpu_object to virtio_gpu_cmd_transfer_to_host_{2d, 3d}

Browse Source 
Pass virtio_gpu_object down to virtio_gpu_cmd_transfer_to_host_2d and
virtio_gpu_cmd_transfer_to_host_3d functions, instead of passing just
the virtio resource handle.

This is needed to lookup the scatter list of the object, for dma sync.
