netns: ip6mr: declare reg_vif_num per-namespace
Preliminary work to make IPv6 multicast forwarding netns-aware. Declare variable 'reg_vif_num' per-namespace, moves into struct netns_ipv6. At the moment, this variable is only referenced in init_net. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>
