Jozsef Kadlecsik 94dd411c18 netfilter: ipset: Fix suspicious rcu_dereference_protected() ...

[ Upstream commit 8ecd06277a7664f4ef018abae3abd3451d64e7a6 ]

When destroying all sets, we are either in pernet exit phase or
are executing a "destroy all sets command" from userspace. The latter
was taken into account in ip_set_dereference() (nfnetlink mutex is held),
but the former was not. The patch adds the required check to
rcu_dereference_protected() in ip_set_dereference().

Fixes: 4e7aaa6b82d6 ("netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type")
