[PATCH net-next 04/11] ipv4: no longer reference init_net in ip4_frags_ns_ctl_table[]

[Eric Dumazet]

(struct net *)->ipv4.fqdir will soon be a pointer, so make
sure ip4_frags_ns_ctl_table[] does not reference init_net.

ip4_frags_ns_ctl_register() can perform the needed initialization
for all netns.
