Tim Chen 59b24e6245 tick/sched: Preserve number of idle sleeps across CPU hotplug events ...

commit 9a574ea906 upstream.

Commit 71fee48f ("tick-sched: Fix idle and iowait sleeptime accounting vs
CPU hotplug") preserved total idle sleep time and iowait sleeptime across
CPU hotplug events.

Similar reasoning applies to the number of idle calls and idle sleeps to
get the proper average of sleep time per idle invocation.

Preserve those fields too.
