ACPI: Fix IASL Warning about unused method for _OSI check
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 22: if(CondRefOf(\_OSI,Local1))
Warning 3144 - ^
Method Local is set but never used (Local1)
