Bug 750625 - Fix Coverity (11062) Resource leak
https://bugzilla.redhat.com/show_bug.cgi?id=750625
plugins/chainingdb/cb_bind.c (chainingdb_bind)
Bug Description: Variable "sdn" going out of scope leaks
the storage it points to. If SLAPI_BIND_TARGET_SDN is not
given (anonymous bind) to cb_bind, sizeof(Slapi_DN) leaks.
Fix Description: Free sdn if the structure Slapi_DN is locally
allocated.
