doc: Call out queue_rcu_work() for blocking RCU callbacks
The current checklist.rst file correctly notes that RCU callbacks execute in BH context, and cannot block. This commit adds words advising people needing callbacks to block to use workqueues, for example, by replacing call_rcu() with queue_rcu_work(). Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
