netfilter: nf_queue: get rid of dependency on IP6_NF_IPTABLES

Browse Source 
hash_v6 is used by both nftables and ip6tables, so depend on
IP6_NF_IPTABLES is not properly.

Actually, it only parses ipv6hdr and computes a hash value, so
even if IPV6 is disabled, there's no side effect too, remove it.
