rcu: Use WRITE_ONCE() for assignments to ->next for rculist_nulls
When the objects managed by rculist_nulls are allocated with
SLAB_TYPESAFE_BY_RCU, old readers may still hold references to an object
even though it is just now being added, which means the modification of
->next is visible to readers. This patch therefore uses WRITE_ONCE()
for assignments to ->next.
