Log:
  MFC r211301:
  
    In rip6_input(), in case of multicast, we might skip the normal processing
    and go to the next iteration early if multicast filtering would decide that
    this socket shall not receive the data.
    Unlock the pcb in that case or we leak the read lock and next time trying
    to get a write lock, would hang forever.
