Add two functions to atomically replace RCU-protected hlist_nulls entries.
Keep using WRITE_ONCE() to assign values to ->next and ->pprev, as
mentioned in the patch below:
commit efd04f8a8b45 ("rcu: Use WRITE_ONCE() for assignments to ->next for
rculist_nulls")
commit 860c8802ace1 ("rcu: Use WRITE_ONCE() for assignments to ->pprev for
hlist_nulls")
