perf stat: Handle bad events in abs_printout()

In the printout() function, it checks if the event is bad (i.e. not
counted or not supported) and print the result.  But it does the same
what abs_printout() is doing.  So add an argument to indicate the value
is ok or not and use the same function in both cases.
