Non-generic devices have numbered_buttons set for both pen and
touch interfaces by default. The actual number of buttons on the
interface is normally manually decided later, which is different
from what those HID generic devices are processed, where number
of buttons are directly retrieved from HID descriptors.

This patch adds the missed HID_GENERIC check and moves the statement
to wacom_setup_pad_input_capabilities since it's not a quirk anymore.
