IPVS: bug in ip_vs_ftp, same list heaad used in all netns.

[ Upstream commit c74c0bfe0b61cf41a897c2444c038e0d3f600556 ]

When ip_vs was adapted to netns the ftp application was not adapted
in a correct way.
However this is a fix to avoid kernel errors. In the long term another solution
might be chosen.  I.e the ports that the ftp appl, uses should be per netns.
