touchpad: reset the edge scroll state on touch up if edge scroll is disabled
If a touch was down (and up again) before the device was switched to edge
scrolling, libinput reported an error message:
litest error: libinput bug: unexpected scroll event 0 in area state
While edge scrolling was disabled, any new touch would be set to the area
state but it was never reset on touch release.
