Count only hardware interrupts in cnt.v_intr, so that the individual
hardware interrupt counts add up to the total. Previously, software
interrupts generated by splz() were counted in the total. These
software interrupts seem to be very rare - there have apparently been
0 of them on freefall among the last 352448857 interrupts.
