rcutorture: Flag nonexistent RCU GP kthread
Currently, if the RCU grace-period kthread has not yet been created, in which case the starvation-check code will print zero for the state, which maps to TASK_RUNNING. This could clearly be quite confusing, so this commit prints ~0, which does not map to any legal ->state value. Signed-off-by: Paul E.
