There is a bug in menu governor where we have
if (data->elapsed_us < data->elapsed_us + measured_us)
with measured_us already having elapsed_us added in tickless case here
unsigned int measured_us =
cpuidle_get_last_residency(dev) + data->elapsed_us;
Also, it should be last_residency, not measured_us, that need to be used to
do comparing and distinguish between expected & non-expected events.
Refactor menu_reflect() to fix these two problems.
