[NETNS][FRAGS]: Make the inet_frag_queue lookup work in namespaces.
Since fragment management code is consolidated, we cannot have the
pointer from inet_frag_queue to struct net, since we must know what
king of fragment this is.
So, I introduce the netns_frags structure. This one is currently
empty, but will be eventually filled with per-namespace
attributes. Each inet_frag_queue is tagged with this one.
The conntrack_reasm is not "netns-izated", so it has one static
netns_frags instance to keep working in init namespace.
