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)
