touchpad: end hovering touches in maybe_end_touch
Otherwise a hovering touch stays around forever even after the finger has discontinued. This doesn't matter on slots, but for fake fingers the finger may suddenly end up being forced down/up as a result of the pressure changes on the real fingers. So when in maybe_end_touch, switch them back to NONE immediately - hovering touches do not need to trigger a TOUCH_END event. https://bugs.freedesktop.org/show_bug.cgi?id=105258 Signed-off-by:Peter Hutterer <peter.hutterer@who-t.net> (cherry picked from commit d8db6b59)
