Trip points with temperature set to THERMAL_TEMP_INVALID are as good as
disabled, so make handle_thermal_trip() ignore them.

This will set the temperature to THERMAL_TEMP_INVALID at each thermal
zone update.
It would make more sense to set it when setting the disabled bit at init
time, no?
But is that something we really want to do ? The trip point will be
reordered due to the temperature change (-273°C)
