rcutorture: Consider FROZEN hotplug notifier transitions
The hotplug notifier rcutorture_cpu_notify() doesn't consider the corresponding CPU_XXX_FROZEN transitions. They occur on suspend/resume and are usually handled the same way as the corresponding non frozen transitions. Mask the switch case action argument with '~CPU_TASKS_FROZEN' to map CPU_XXX_FROZEN hotplug transitions on corresponding non-frozen transitions. Cc: Josh Triplett <josh@joshtriplett.org> Cc: "Paul E.
