[ Upstream commit 934c5b32a5e43d8de2ab4f1566f91d7c3bf8cb64 ]
The correct way for legacy drivers to update properties that need to do a full modeset, is to do a full modeset.
Note that we don't need to call the drm_mode_config_internal helper because we're not changing any of the refcounted paramters.
v2: Fixup error handling (Ville). Since the old code didn't bother I decided to just delete it instead of adding even more code for just error handling.
