Certain sensors like thermistor's, can read temperature higher than the threshold even before a threshold violation uevent. This is because certain thermistor's use comparator's to trigger threshold violation independent of the ADC used to read the temperature. In those corner case, thermal HAL can update the severity when a client is reading a temperature and not notify them. So when an actual uevent occurs, client notification will be skipped, because the severity wouldn't have changed. Update HAL to notify clients when the read temperature API see's the threshold violation first before the uevent. Change-Id: I30248b1364909a74b362fa732041c3f96917952c
