On idle exit the dyntick-idle accounting accounts the time up to now,
then the tick is restarted on its old period. The first tick accounts a
whole TICK_NSEC to whatever runs, although the part of that period
before the idle exit has just been accounted as idle time, or with
IRQ_TIME_ACCOUNTING as IRQ time. That is up to a full tick per idle
exit, and /proc/stat reports more idle time than wall time.
Record how much of the current tick period dyntick-idle has accounted,
and leave it out of the tick that ends the period.
