Log:
  Fix a dead store.
  
  We would fail to clear DNS search list configuration if a router
  stopped specifying the DNSSL RA option.  I suspect that the bug
  was mostly harmless, as the RDNSS and DNSSL options are typically used
  together and omitting the RDNSS option would have the same effect.
