[PATCH] alienware-wmi: Adjust instance of all wmi_evaluate_method calls to 0

From: Mario Limonciello
Date: Wed Jun 21 2017 - 18:01:55 EST


Pali recently noticed that WMI instances are zero indexed.

The only reason that these calls all worked properly is because the ASL
didn't verify the instance number.
