Florian Westphal 2a43ecf96b netfilter: nf_tables: avoid global info storage
This works because all accesses are currently serialized by nfnl
nf_tables subsys mutex.

If we want to have per-netns locking, we need to make this scratch
area pernetns or allocate it on demand.

This does the latter, its ~28kbyte but we can fallback to vmalloc
so it should be fine.
