s4:descriptor LDB module - a bit cleanup
- add more OOM checks where needed - remove message of an error which cannot happen anymore (since now the structural objectclass is always checked by the objectclass LDB module) Autobuild-User: Matthias Dieter Wallnöfer <mdw@samba.org> Autobuild-Date: Wed Nov 3 18:30:52 UTC 2010 on sn-devel-104
