ACPICA: Fix a regression for deletion of Alias() objects.

Browse Source 
Fixes a regression introduced by commit e23d9b8297 (ACPICA:
Namespace: Properly null terminate objects detached from a namespace
node)

In the case of Alias namespace nodes, the node simply points to the aliased
node via the Object field; thus we cannot assume that the object is an
operand object.
