6.12-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit b5e65ae557da9fd17b08482ee44ee108ba636182 ]
This device sometimes doesn't send touch release signals when moving from >=2 fingers to <2 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
