HID: make Wacom modesetting failures non-fatal
With Wacom tablet mode-setting moved from userspace into kernel,
we don't have to consider failures of device queries through the
_raw callback as hard failure, as the driver can safely continue
anyway.
This is consistent with the current USB driver in wacom_sys.c
