smbd/service_stream: connection processing flag is not really bool

The warning is:

../source4/smbd/service_stream.c: In function ‘stream_io_handler’:
../source4/smbd/service_stream.c:94:18: warning: increment of a boolean expression [-Wbool-operation]
  conn->processing++;
                    ^~
../source4/smbd/service_stream.c:100:18: warning: decrement of a boolean expression [-Wbool-operation]
  conn->processing--;
                    ^~

while the code in question looks like:

	conn->processing++;
	if (flags & TEVENT_FD_WRITE) {
		conn->ops->send_handler(conn, flags);
	} else if (flags & TEVENT_FD_READ) {
		conn->ops->recv_handler(conn, flags);
	}
	conn->processing--;

If this is never going to be nested, processing can be bool and the ++
and -- can be true/false assignments. But it seems possible that these
might be nested so it is better to go the other way.
