ACPICA: ACPICA: Fix for _INI regression

This change fixes a problem introduced by recent commit c34c82b
(ACPICA: Predefine names: Add allowed argument types to master info
table) in 20130328 where _INI methods are no longer executed properly
because of a memory block that is not initialized properly.  ACPICA
