drm: legacy: issue a NULL modeset on disable
The DRM subsystem needs a NULL modeset for connectors which disappear
from the system to disable the hardware pipes, otherwise the pixels get
rendered but are sent nowhere.
The atomic backend does the equivalent by removing the properties and
issuing a commit.
Fixes #1706
