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.
