[PATCH V2 06/14] perf tools: Fix missing thread_map__put in perf_evlist__propagate_maps

[Adrian Hunter]

perf_evlist__propagate_maps() incorrectly assumes evsel->threads
is NULL before reassigning it, but it won't be NULL when
perf_evlist__set_maps() is used to set different (or NULL) maps.
Thus thread_map__put must be used, which works even if
evsel->threads is NULL.
