hwmon: (pwm-fan) Disable PWM if fetching cooling data fails
commit 53f1647da3e8fb3e89066798f0fdc045064d353d upstream.
In case pwm_fan_of_get_cooling_data() fails we should disable the PWM
just like in the other error cases.
Fixes: 2e5219c77183 ("hwmon: (pwm-fan) Read PWM FAN configuration from device tree")
