backend/drm: require buffer on modeset in drm_connector_test
When testing a modeset, make sure the caller has also provided a
buffer. This allows df0e75ba05e2 ("output: try skipping buffer
allocation if the backend allows it") to work as expected with the
DRM backend.
Closes: https://github.com/swaywm/wlroots/issues/3086
