[PATCH 3/4] drm: Don't prune modes loudly when a connector is disconnected

[Damien Lespiau]

drm_helper_probe_single_connector_modes() is responsible for pruning the
previously detected modes on a disconnected connector. We don't really
need to log, again, the full list of modes that used to be valid when
connected.
