drm/i915: Don't change the status of forced connectors during HPD poll detect

Browse source

As described in the previous patch a connector shouldn't change its
status while it's forced to a connected/disconnected state. This can
still happen while running the connector detect function to account for
lost HPD events in a low-power state.

Fix this by reusing the connector detect function which handles a
hotplug event and prevents updating the status for forced connectors as
expected.
