cpus: Introduce cpu_list_generation_id
Introduce cpu_list_generation_id to track cpu list generation so
that cpu hotplug/unplug can be detected during measurement of
dirty page rate.
cpu_list_generation_id could be used to detect changes of cpu
list, which is prepared for dirty page rate measurement.
