    kernel - Fix getsockname() on unnamed AF_LOCAL sockets
    
    * Fix getsockname() on unnamed AF_LOCAL sockets.  The socket structure
      does not actually bother storing a sockaddr, so sa is returned NULL.
      In this situation, just dummy-up an AF_LOCAL sockaddr.
    
    * Don't bother copyout()ing sa_len unless it has changed.
