thermal: testing: Use DEFINE_FREE() and __free() to simplify code
[ Upstream commit 1c426fd09ca85fb77f120f7933e39eb9df99a39a ]
Use DEFINE_FREE() to define a __free function for dropping thermal
zone template reference counters and use it along with __free() to
simplify code in some places.
No intentional functional impact.
