Eric Dumazet 684880d89a inet: frags: call inet_frags_fini() after unregister_pernet_subsys()
[ Upstream commit ae7352d384a552d8c799c242e74a934809990a71 ]

Both IPv6 and 6lowpan are calling inet_frags_fini() too soon.

inet_frags_fini() is dismantling a kmem_cache, that might be needed
later when unregister_pernet_subsys() eventually has to remove
frags queues from hash tables and free them.

This fixes potential use-after-free, and is a prereq for the following patch.

Fixes: d4ad4d22e7 ("inet: frags: use kmem_cache for inet_frag_queue")
