[PATCH 2/3] thermal: core: Reorder 'thermal_zone_device_register()' error handling code

[Christophe JAILLET]

Reorder code in the error handling path in order to match the way resources
have been allocated.

With this new order, we can avoid a call to 'device_unregister()' if
'thermal_zone_create_device_groups'()' fails. At this point,
'device_register()' has not been called yet.
