types: Remove call_rcu_bh() and call_rcu_sched()
Now that call_rcu()'s callback is not invoked until after bh-disable and
preempt-disable regions of code have completed (in addition to explicitly
marked RCU read-side critical sections), call_rcu() can be used in place
of call_rcu_bh() and call_rcu_sched(). This commit therefore removes
these two API members from the callback_head structure's header comment.
