drm/atomic-helper: Disable appropriate planes in disable_planes_on_crtc()
Currently, the helper drm_atomic_helper_disable_planes_on_crtc() calls
->atomic_disable for all planes _to be_ enabled on a particular CRTC.
This is obviously wrong for those planes which are not scanning out frames
when the helper is called. Instead, it's sane to disable active planes
of old_crtc_state in the helper.
