ipvs: fix active FTP
- Do not create expectation when forwarding the PORT command to avoid blocking the connection. The problem is that nf_conntrack_ftp.c:help() tries to create the same expectation later in POST_ROUTING and drops the packet with "dropping packet" message after failure in nf_ct_expect_related. - Change ip_vs_update_conntrack to alter the conntrack for related connections from real server. If we do not alter the reply in this direction the next packet from client sent to vport 20 comes as NEW connection. We alter it but may be some collision happens for both conntracks and the second conntrack gets destroyed immediately. The connection stucks too.
