Jozsef Kadlecsik 8ecd06277a netfilter: ipset: Fix suspicious rcu_dereference_protected() 
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: 4e7aaa6b82 ("netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type")
