When a CRTC is going to be disabled, it's state may contain a display mode with zeroed content. This could be reproduced by HDMI cable hotplug out operation with legacy fbdev support in dual display cases. It would confuse driver's CRTC callback ->mode_fixup and make the total state be rejected. So, let's don't call the callback for the CRTC.
