[PATCH] rcutorture: catchup doc fixes for idle-hz tests
This just catches the RCU torture documentation up with the recent fixes that test RCU for architectures that turn of the scheduling-clock interrupt for idle CPUs and the addition of a SUCCESS/FAILURE indication, fixing up an obsolete comment as well.
