In drm_mode_getconnector we send the connector status back to
userspace. However, we only return the last detected status, rather
than performing status detection again, which can lead to trouble if
the configuration changes after module load and initial probing is
done. Since drm_mode_getconnector currently has full probe semantics,
make it return a current status at all times so that config changes are
properly picked up.
