[PATCH 2/2] thermal/governors: Fix cooling device setting cooling state failure

[Qibo Huang]

Because the __thermal_cdev_update function traverses the
cooling_device->thermal_instances list to obtain the maximum
target state, and then the cooling device sets the maximum
cooling state. However, the power_actor_set_power function
only updates the target value of thermal_zone->thermal_instances
to the target state, and does not update the target value of
cooling_device->thermal_instances, resulting in the target
being 0 all the time.
