msm-core: Disable sensor threshold trip during suspend

Disable sensor threshold trip during suspend rather
than a threshold cancel. This is required since cancel
threshold would remove the threshold pointer from
thermal core driver. This would corrupt the sensor
threshold list if there is a sensor threshold interrupt
at the same time.
