Subject: [PATCH RFC 5/5] doc: rcu: Encourage use of rcu_barrier in checklist

The checklist suggests rcu_barrier_bh for RCU-bh and similarly for
sched, however these APIs are now implemented as rcu_barrier itself due
to the RCU consolidation. It may also be removed in the future, so lets
correct the doc to encourage use of the rcu_barrier() API itself.
Similar changes are made in previous patches.

 	You instead need to use one of the barrier functions:
 
 	o	call_rcu() -> rcu_barrier()
-	o	call_rcu_bh() -> rcu_barrier_bh()
-	o	call_rcu_sched() -> rcu_barrier_sched()
+	o	call_rcu_bh() -> rcu_barrier()
+	o	call_rcu_sched() -> rcu_barrier()
 	o	call_srcu() -> srcu_barrier()
 
 	However, these barrier functions are absolutely -not- guaranteed
