monitor-manager-kms: Disable CRTCs if there is no monitor

Browse Source 
After last monitor gets unplugged from the system, hotplug detection may
no longer work on Intel GFX.

This is because we didn't trigger a modeset to disable CRTCs, and i915
requires it to make hotplug detection continue to work [1].

Ensure disabled CRTCs are unset and post a modeset to disable them.
