PATCH 1/1 ACPICA: Fix possible fault in return package object repair code

From: Bob Moore <[email protected]>

Fixes a problem that can occur when a lone package object is wrapped with an outer package object in order to conform to the ACPI specification. Can affect these predefined names:
_ALR,_MLS,_PSS,_TRT,_TSS,_PRT,_HPX,_DLM,_CSD,_PSD,_TSD
