Comment:

 Some further context shows that this code is already correct:
 {{{
   if ((circ->_base.purpose != CIRCUIT_PURPOSE_C_REND_READY &&
        circ->_base.purpose != CIRCUIT_PURPOSE_C_REND_READY_INTRO_ACKED)
       || !circ->build_state->pending_final_cpath) {
     log_warn(LD_PROTOCOL,"Got rendezvous2 cell from hidden service, but
 not "
              "expecting it. Closing.");
     circuit_mark_for_close(TO_CIRCUIT(circ), END_CIRC_REASON_TORPROTOCOL);
     return -1;
   }
 }}}
