HID: wacom: Short-circuit processing of touch when it is disabled

Avoid doing unnecessary work when touch is disabled by detecting this
condition and returning early. Note that the probe process sends GET
FEATURE requests to discover e.g. HID_DG_CONTACTMAX, so we can't start
ignoring touch reports until probe finishes.
