This reverts commit e0be9eab47d621545e5498c32c0fef39f7ef84a9.

This change is now producing problems on IPv6-enabled systems as it will
deny access to any website that is IPv6-enabled as well, even if the
client connected using IPv4.

I have tested if squid is now running on fine on systems where IPv6 is
disabled and can confirm that its running just fine.
