HID: wacom: don't apply generic settings to old devices
[ Upstream commit e7deb1570a527d3c74be4e21a72b1b459605c501 ] 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.
