thermal/core: Fix memory leak in the error path

Browse Source 
commit d44616c6cc3e35eea03ecfe9040edfa2b486a059 upstream.

Fix the following error:

 smatch warnings:
 drivers/thermal/thermal_core.c:1020 __thermal_cooling_device_register() warn: possible memory leak of 'cdev'

by freeing the cdev when exiting the function in the error path.
