- Fix a crash on a rpc entry when an IPv6 address is explicitly specified

in -a flag.

- Fix a bug that sockaddr_in was used where sockaddr_in6 should have
  been used.  This was not actually harmful because offsetof(struct
  sockaddr_in, sin_port) is equal to offsetof(struct sockaddr_in6,
  sin6_port).
