netfilter: nf_ct_pptp: fix DNATed PPTP connection address translation

When both the server and the client are NATed, the set-link-info control packet containing the peer's call-id field is not properly translated. I have verified that it was working in 2.6.16.13 kernel previously but due to rewrite, this scenario stopped working (Not knowing exact version when it stopped working).
