thermal: remove unnecessary call to thermal_zone_device_set_polling
When the thermal zone has no get_temp callback then thermal_zone_device_register() calls thermal_zone_device_set_polling() with a polling delay of 0. This only cancels the poll_queue. Since the poll_queue hasn't been scheduled this is a no-op. Remove it.
