Eric Dumazet 8cc20198cf netfilter: nf_conntrack: death_by_timeout() fix 
death_by_timeout() might delete a conntrack from hash list
and insert it in dying list.

 nf_ct_delete_from_lists(ct);
 nf_ct_insert_dying_list(ct);

I believe a (lockless) reader could *catch* ct while doing a lookup
and miss the end of its chain.
(nulls lookup algo must check the null value at the end of lookup and
should restart if the null value is not the expected one.
cf Documentation/RCU/rculist_nulls.txt for details)

We need to change nf_conntrack_init_net() and use a different "null" value,
guaranteed not being used in regular lists. Choose very large values, since
hash table uses [0..size-1] null values.
