Update documentation comment for rend_client_reextend_intro_circuit

Browse Source 
One of its callers assumes a non-zero result indicates a permanent failure
(i.e. the current attempt to connect to this HS either has failed or is
 doomed).  The other caller only requires that this function's result
never equal -2.

Bug reported by Sebastian Hahn.
