lustre/lov: avoid subobj's coh_parent race
* during a file lov object initialization, we need protect the access
and change of its subobj->coh_parent, since it could be another
layout change race there, which makes an unreferenced lovsub obj in
the site object hash table.
* dump lovsub objects in the site if the lovsub device reference > 0
during its finalization phase.
