tick: Assume the tick can't be stopped in NOHZ_MODE_INACTIVE mode
The full-nohz update function checks if the nohz mode is active before proceeding. It considers one exception though: if the tick is already stopped even though the nohz mode is inactive, it still moves on in order to update/restart the tick if needed. However in order for the tick to be stopped, the nohz_mode has to be either NOHZ_MODE_LOWRES or NOHZ_MODE_HIGHRES. Therefore it doesn't make sense to test if the tick is stopped before verifying NOHZ_MODE_INACTIVE mode. Remove the needless related condition.
