ACPI: Fix IASL Warning about unused method for _TZ checks

According to the ACPI Spec for CondRefOf, the result argument is
optional.  In all of these locations, it was getting set but not
used, creating a warning in new versions of IASL.  Since it's
an optional argument, just remove it.

dsdt.aml 640:              If (CondRefOf (^GBUF, Local0)) {
Warning  3144 - Method Local is set but never used ^  (Local0)
