Subject: config-delete overlay fixes

- unregister controls when removing overlays from cn=config (syncprov,
  ppolicy, valsort, chain and sssvlv)
- Send error to active psearches upon syncprov overlay removal
- syncprov: reset BackendInfo to original value after checkpoint. Leaks memory
  otherwise (with -DSLAP_CONFIG_DELETE)
