[PATCH v3 3/4] drm/virtio: batch resource creation

[Gerd Hoffmann]

Move virtio_gpu_notify() to higher-level functions for
virtio_gpu_cmd_create_resource(), virtio_gpu_cmd_resource_create_3d()
and virtio_gpu_cmd_resource_attach_backing().

virtio_gpu_object_create() will batch commands and notify only once when
creating a resource.
