Mitchell Horne edcf9e59c3 pmcstat: set initial counter value to zero 
For an infrequent event, pmcstat may report (u_long)-1 for CPUs where
the counter was never incremented. Just set this to zero, instead.

ev->ev_count is passed as the 'count' argument to pmc_allocate(3), but
this wasn't always the case.
