input: touchscreen: hxchiset: fix bug in interrupt handler 



Fix bug in interrupt handler which is not sending the proper
events for TRACKING_ID. TRACKING_ID was always coming as zero,
which is needed to be as incremented count value for every finger
touch activity, and it is fixed by properly aligning the events
as required.
