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. This commit therefore corrects checklist.txt
to encourage use of the underlying rcu_barrier() API.

		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
