Regression fix for systemd getting confused about unknown connector state
after resume. Just stop setting the state to unknown, turned out to be a
silly idea anyway. What drivers imo really should do (and i915 still does
that) is forcing a full reprobe on resume to make sure connector changes
while suspended are caught. Most drivers seem to get this wrong. Otoh it
took us years to get fixes merged where some probe races resulted in
eating uevents, I guess userspace expectations for reliable hpd are just
really low :(
