drm/gud: don't keep a connector without a CRTC as connector_state

If the 'for_each_new_connector_in_state()' loop finishes without
hitting the break, connector_state is left pointing at the last
connector visited, which has no CRTC, instead of
staying NULL.

That skips the "if (!connector_state)" fallback below the loop, which
looks up the active connector when the state contains none. The
function then carries on with a connector that is not driven.

Fix by resetting connector_state to NULL for each connector visited that
has no CRTC, so that it is NULL when none was found and the fallback runs.
