LU-5648 ofd: In destroy orphan case always let MDS know last id

It appears that if we think MDS asked us to delete too many
precreate objects (more than 2 MAX_PRECREATE counts)
then we don't do the precreation, but do not let MDS know it needs
to advance the last_id forward by quite a bit.
This lead to reassigning these objects to other files after recovery.
