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’ 
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’ 

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