thermal/drivers/devfreq_cooling: Fix wrong return on error path

The following error is reported by kbuild:

 smatch warnings:
 drivers/thermal/devfreq_cooling.c:433 of_devfreq_cooling_register_power() warn: passing zero to 'ERR_PTR'

Fix the error code by the setting the 'err' variable instead of 'cdev'.
