4.14-stable review patch. If anyone has any objections, please let me know.
------------------
This reverts commit 28c74ff85efd192aeca9005499ca50c24d795f61.
>From Florian Westphal <f...@strlen.de>:
It causes kernel crash for locally generated ipv6 fragments
when netfilter ipv6 defragmentation is used.
The faulty commit is not essential for -stable, it only
delays netns teardown for longer than needed when that netns
still has ipv6 frags queued. Much better than crash :-/
