[PATCH] drm: atomic: fix legacy gamma set helper

[Lionel Landwerlin <lionel.g.landwerlin@intel.com>]

Color management properties are a bit of an odd use case because
they're not marked as atomic properties. Currently we're not updating
the non atomic values so the drm_crtc_state is out of sync with the
values stored in the crtc object.
