perf kvm stat live: Use perf_evlist__add_pollfd return fd position
With the interface changed in following commit:
2171a9256862 tools lib fd array: Allow associating an integer cookie with each entry
the perf_evlist__add_pollfd function now returns the fd position in the
pollfd array.
Hence we no longer need to count the fd position, because we get it as
the return value.
