    Avoid redundant socket cleanup in sendto_kdc.c
    
    Since r25120, kill_conn() has been responsible for closing and
    invalidating conn->fd.  In the unlikely event that the KDC sends a TCP
    response to us before we send a TCP request, we were cleaning up the
    socket again, which is useless (though also harmless).  Get rid of
    that code.
