Fix rpcbind init after r300941.

Browse Source 
- getaddrinfo() sets res = NULL on failure and freeaddrinfo() always
  dereferences its argument, so we should only free the address list after
  a successful call.
- Address a second potential leak caused by getaddrinfo(AF_INET6)
  overwriting the address list returned by getaddrinfo(AF_INET).
