platform/x86: alienware-wmi: Adjust instance of wmi_evaluate_method calls to 0
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. Signed-off-by: Mario Limonciello <mario.limonciello@dell.com> Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>
