gh-100795: Don't call freeaddrinfo on failure. (#101252)

When getaddrinfo returns an error, the output pointer is in an unknown state
Don't call freeaddrinfo on it.  See the issue for discussion and details with
links to reasoning.  _Most_ libc getaddrinfo implementations never modify the
output pointer unless they are returning success.
