[PATCH] netfilter/ipvs: Fix unused variable warning

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Move the local variable 'ret' into the IP_VS_IPV6 ifdef so that the
unused variable warning doesn't fire for randconfig builds with
CONFIG_IP_VS_IPV6 disabled.

Fixes: 098e13f5b21d ("ipvs: fix dependency on nf_defrag_ipv6")
