Prevent processing touch after receiving an invalid tracking id
Touch driver would send an INVALID_TRACKING_ID value when touch
released from touch screen. That tells input framework should send an
up or pointer up event and stop processing the pointer, so if any
unexpected data is also updating from driver side, we have to prevent
it becomes as a valid pointer.
