cpuidle: Menu governor fix wrong usage of measured_us
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.
