ipv6: blackhole_netdev needs snmp6 counters
Whenever rt6_uncached_list_flush_dev() swaps rt->rt6_idev
to the blackhole device, parts of IPv6 stack might still need
to increment one SNMP counter.
Root cause, patch from Ido, changelog from Eric :)
This bug suggests that we need to audit rt->rt6_idev usages
and make sure they are properly using RCU protection.
