ldap_back_extended_one needs to play with op->o_ctrls since it doesn't just pass ctrls over like the other sites in back-ldap, but it never sets oldctrls as is should.
If a control is ever added to the list, it will restore op->o_ctrls to the wrong value and crash. This happens e.g. in certain chaining scenarios with mode=legacy.
