 If relay process extent request then it can to fill logs by warnings about
 wrongly formatted create cells. It's easy to reproduce such cells and to
 trigger logs for relay.
 {{{
   if (r < 0) {
     log_warn(LD_CIRC,"Couldn't format create cell");
     return -1;
   }
 }}}
 It need lower logs level or rate limiting or LOG_PROTOCOL_WARN
 (preferable) for relayed cells.
