Input: wacom - use per-device instance of wacom_features

Since we mangle data in wacom_features when dealing with certain devices let's
use a private (per-device) instance of wacom_features in wacom_wac. This way
same product ID can support more than one type of device, such as pen and touch,
and not interfere with each other.
