[PATCH nf-next 55/84] ipvs: Pass ipvs not net to register_ip_vs_app and unregister_ip_vs_app

[Simon Horman <horms@xxxxxxxxxxxx>]

From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>

Also move the tests for net_ipvs being NULL into __ip_vs_ftp_init
and __ip_vs_ftp_exit.  The only places where they possibly make
sense.
