commit 476d60b1b4c8a2b14a53ef9b772058f35e604661 upstream.
The thermal handle object may fail initialization when the module is
loaded in the first place. Avoid attempting to use it on resume then.
Fixes: 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer objects for
ASL create_field() operator")
