[PATCH] netfilter: nfnetlink_queue: Unregister pernet subsys in case of init failure

[Nikolay Borisov <kernel@kyup.com>]

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.

Fixes: 3bfe049807c2403 ('netfilter: nfnetlink_{log,queue}: Register
						pernet in first place')
