ipv6: add sysctl_ipv6_flowlabel group
Group together following struct netns_sysctl_ipv6 fields:
- flowlabel_consistency
- auto_flowlabels
- flowlabel_state_ranges
After this patch, ip6_make_flowlabel() uses a single cache line to fetch
auto_flowlabels and flowlabel_state_ranges (instead of two before the patch).
