Subject: [PATCH 09/13] netfilter: nf_conntrack_h323: Remove deprecated config check

From: Subash Abhinov Kasiviswanathan <subashab@...eaurora.org>

CONFIG_NF_CONNTRACK_IPV6 has been deprecated so replace it with a check
for IPV6 instead.

Use nf_ip6_route6() instead of v6ops->route() and keep the IS_MODULE()
in nf_ipv6_ops as mentioned by Florian so that direct calls are used
when IPV6 is builtin and indirect calls are used only when IPV6 is a
module.

Fixes: a0ae2562c6c4b2 ("netfilter: conntrack: remove l3proto abstraction")
