ipvs: fix warning on unused variable
When CONFIG_IP_VS_IPV6 is not defined, build produced this warning:
net/netfilter/ipvs/ip_vs_ctl.c:899:6: warning: unused variable ‘ret’ [-Wunused-variable]
int ret = 0;
^~~
Fix this by moving the declaration of 'ret' in the CONFIG_IP_VS_IPV6
section in the same function.
While at it, drop its unneeded initialisation.
