    wg: Implement wg_peer_{set,get}_endpoint() to set the remote endpoint
    
    Moving the setting and getting the peer remote endpoint to their own
    separate functions.  This cleans up the already lengthy
    wg_ioctl_{set,get}() functions.
    
    In addition, these two functions fix the following two issues:
    - The 'p_endpoint_lock' wasn't acquired before setting/getting the
      endpoint address.
    - The local address 'e_local' wasn't cleared when setting the remote
      endpoint address.
