drm: Stop resetting connector state to unknown
It's causing piles of issues since we've stopped forcing full detect
cycles in the sysfs interfaces with

drm: Lighten sysfs connector 'status'
The original justification for this was that the hpd handlers could
use the unknown state as a hint to force a full detection. But current
i915 code isn't doing that any more, and no one else really uses reset
on resume. So instead just keep the old state around.
