ACPI: WMI: Set instance for query block calls

Although the necessary data structure was set up, it was never actually
passed in, so data block calls have only been working by sheer chance.

(On Acer laptops. the data block methods we've been calling never look at
the instance value, hence acer-wmi never triggered this before).

f3454ae8104efb2dbf0d08ec42c6f5d0fe9225bc brought this to light.
