Guenter Roeck 5696e4aaab hwmon: (pwm-fan) Check return value from devm_add_action_or_reset ...

devm_add_action_or_reset() can fail due to a memory allocation failure.
Check for it and return the error if that happens.

Fixes: 37bcec5d9f ("hwmon: (pwm-fan) Use devm_thermal_of_cooling_device_register")
