ipvs: Remove possibly unused variables from ip_vs_conn_net_{init,cleanup}

If CONFIG_PROC_FS is undefined then the arguments of proc_create()
and remove_proc_entry() are unused. As a result the net variables of
ip_vs_conn_net_{init,cleanup} are unused.

net/netfilter/ipvs//ip_vs_conn.c: In function ‘ip_vs_conn_net_init’:
net/netfilter/ipvs//ip_vs_conn.c:1350:14: warning: unused variable ‘net’ [-Wunused-variable]
net/netfilter/ipvs//ip_vs_conn.c: In function ‘ip_vs_conn_net_cleanup’:
net/netfilter/ipvs//ip_vs_conn.c:1361:14: warning: unused variable ‘net’ [-Wunused-variable]
...

Resolve this by dereferencing net as needed rather than storing it
in a variable.

Fixes: 3d99376689ee ("ipvs: Pass ipvs not net into ip_vs_control_net_(init|cleanup)")
