Palm ejection stops working on some Elan and Synaptics touchpad after
commit 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for
some devices").
The commit changes the mt_class from MT_CLS_WIN_8 to
MT_CLS_WIN_8_FORCE_MULTI_INPUT, so MT_QUIRK_CONFIDENCE isn't applied
anymore.
So also apply the quirk since MT_CLS_WIN_8_FORCE_MULTI_INPUT is
essentially MT_CLS_WIN_8.
Fixes: 40d5bb87377a ("HID: multitouch: enable multi-input as a quirk for some devices")
