assert listen.c:573 in -s or -X mode

[Joe Maimon]

happens frequently if I am stepping through requests, infrequently if it 
  is running w/o breakpoints

SO i changed the code to this

static int auth_socket_send(rad_listen_t *listener, REQUEST *request)
{
         if(request->proxy_listener == listener)
                 rad_assert(request->proxy_listener == listener);
         else
         {
                 rad_assert(request->listener == listener);
                 rad_assert(listener->send == auth_socket_send);
         }


cause it appears that proxy send trips this.

Thanks,

Joe
