drm/radeon: update lockup tracking when scheduling in empty ring
commit 8444d5c69549aa0f0b574cc608742d4669e1cc01 upstream.
There might be issue with lockup detection when scheduling on an
empty ring that have been sitting idle for a while. Thus update
the lockup tracking data when scheduling new work in an empty ring.
