kern/clock: remove interrupt reporting from watchdog_fire()

Browse Source 
The interrupt counts may have been valuable in the past, but now DDB can
readily provide them via 'show intrcnt'. This is one of the only
consumers of these counter arrays outside of the interrupt code itself,
and this should be avoided.
