kms/connector: Properly predict connectors turning off

Browse Source 
The connector state wasn't properly predicted, as it earlied out if
the connector wasn't part of a mode set connector list.

Instead use the old CRTC to check whether it was used in any mode set,
and whether the connector was part of any new mode set, to predict
whether the connector is inactive or active.
