[PATCH 1/1] IPVS: seq_release_net should be used.

[Hans Schillstrom <hans.schillstrom@xxxxxxxxxxxx>]

Without this patch every access to ip_vs in procfs will increase
the netns count i.e. an unbalanced get_net()/put_net().
(ipvsadm commands also use procfs.)
The result is you can't exit a netns if reading ip_vs_* procfs entries.
