PATCH: fix getnameinfo

[aafbsd]

getnameinfo() is not called properly for IPv4 (didn't check v6).

You might also want to check the result code, call gai_strerror() and inform the user if s.th. goes wrong

Could you create a pull request?

I am no real git or github user so this is a first wild guess. Whatever I messed up should be fixable. Constructive criticism is always welcome :-).

@schweikert you can close this issue. That fixed with pull request #227
