4.2.8-ckt2 -stable review patch. If anyone has any objections, please let me know.

From: Nikolay Borisov <kernel@xxxxxxxx>
commit 639e077b43d9c54ffb1e1b54a2de54597ceae1d8 upstream.
Commit 3bfe049807c2403 ("netfilter: nfnetlink_{log,queue}:
Register pernet in first place") reorganised the initialisation
order of the pernet_subsys to avoid "use-before-initialised"
condition. However, in doing so the cleanup logic in nfnetlink_queue
got botched in that the pernet_subsys wasn't cleaned in case
nfnetlink_subsys_register failed. This patch adds the necessary
cleanup routine call.
