From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Make __thermal_zone_device_update() bail out if update_temperature() fails to update the zone temperature because __thermal_zone_get_temp() has returned an error and the current zone temperature is THERMAL_TEMP_INVALID (user space receiving netlink thermal messages, thermal debug code and thermal governors may get confused otherwise).

New patch in v2.
