perf kvm stat live: Fix perf_evlist__add_pollfd error handling

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.

We need to change this function's error check condition.
