Eric Dumazet 9ce7bc036a netfilter: ipv6: nf_defrag: reduce struct net memory waste
It is a waste of memory to use a full "struct netns_sysctl_ipv6"
while only one pointer is really used, considering netns_sysctl_ipv6
keeps growing.

Also, since "struct netns_frags" has cache line alignment,
it is better to move the frags_hdr pointer outside, otherwise
we spend a full cache line for this pointer.

This saves 192 bytes of memory per netns.

Fixes: c038a767cd ("ipv6: add a new namespace for nf_conntrack_reasm")
