drm/msm/dp: add missing drm_edid_connector_update() before add_modes on cached EDID

Browse source

After the refactor to struct drm_edid, the fast path in
msm_dp_panel_get_modes() that already held a cached EDID called
drm_edid_connector_add_modes() directly without first calling
drm_edid_connector_update().

The new API requires the update step to associate the EDID with the
connector. Add the missing call. This restores correct behaviour for
the cached-EDID path.
