drm/i915: fix OOPS in lid_notify
and the fact that this forced restore required a w/a list should
have been hint enough that somethings wrong. With the new modeset
infrastructure we can detect when something is amiss (and if required
should be able to take a much more measured approach in any corrective
actions we take).
So let's just kill this.
