commit 9ce7bc036ae4cfe3393232c86e9e1fea2153c237 upstream.
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: c038a767cd69 ("ipv6: add a new namespace for nf_conntrack_reasm")
