platform/x86: dell-pc: avoid double free and invalid unregistration
If platform_profile_register() fails it does kfree(thermal_handler) and
leaves the pointer value around.
Any call to thermal_cleanup() will try to kfree(thermal_handler) again.
This will happen right away in dell_init().
In addition, platform_profile_remove() will be called although no
profile is registered.
NULL out the thermal_handler, so thermal_cleanup() avoids the double free.
