[PATCH] acer-wmi: remove useless input argument for internal wmi

["Lee, Chun-Yi" <joeyli.kernel@xxxxxxxxx>]

From: "Lee, Chun-Yi" <jlee@xxxxxxxx>

The "wmi_interface *iface" is a useless input argument for internal wmi get/set
functions, remove it to clear up source code.

Tested on Lenovo E520.
Tested on Acer TravelMate 4750.
