drm/i915: Don't check modeset state in the hw state force restore path

Browse source

Since the force restore logic will restore the CRTCs state one at a

operation finishes. A call to intel_modeset_check_state() is done once
it's over, so don't check the state multiple times in between. This
regression was introduced in:
