torture: Delay CPU-hotplug operations until boot completes
CPU-hotplug operations invoke stop-machine, which can hog CPUs, which is not a great thing to do before boot has completed. This commit therefore makes the CPU-hotplug operations hold off until boot has completed. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
