Looks like there might already be a problem using evsel->threads instead of
evlist->threads with the logic relating to evsel->system_wide getting lost -
but that happened already in "perf evlist: Factor
perf_evlist__(enable|disable) functions".  Probably the threads should not
be propagated in that case, but it needs more investigation.  I will try to
look at it today.
