[PATCH 1/4] HID: multitouch: add MT_QUIRK_NOT_SEEN_MEANS_UP to MT_CLS_WIN_8 quirks

[Joey Pabalinas]

The firmware found in the touch screen of the Surface Pro 3 is slightly
buggy and occasionally doesn't send lift off reports for contacts; add
MT_QUIRK_NOT_SEEN_MEANS_UP to .quirks to compensate for the missed
reports.
