rcutorture: Remove the "rcu_bh" and "sched" torture types
Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the "rcu_bh" and "sched" torture types from rcutorture. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
