netns: ip6mr: dynamically allocate mfc6_cache_array
Preliminary work to make IPv6 multicast forwarding netns-aware.
Dynamically allocates IPv6 multicast forwarding cache, mfc6_cache_array,
and moves it to struct netns_ipv6.
At the moment, mfc6_cache_array is only referenced in init_net.
Replace 'ARRAY_SIZE(mfc6_cache_array)' with mfc6_cache_array size: MFC6_LINES.
