daemon: handle gethostbyname() error

If the user-supplied hostname can't be found then we should not use it.
We already avoid doing that in the non-NO_IPV6 case by checking if the
return value of getaddrinfo() is zero (success).  Do the same in the
NO_IPV6 case and make sure the return value of gethostbyname() isn't
NULL before dereferencing this pointer.
