thermal: rcar_thermal: Always update thermal zone on interrupt
Since commit a1ade5653804b8eb ("thermal: rcar: check every
rcar_thermal_update_temp() return value") the temperature is always read
in rcar_thermal_get_current_temp() so comparing it before and after
enabling interrupts have little effect. Remove the check and always
update the thermal zone when we get an interrupt that the temperature
have changed.
