perf evlist: Fix missing thread_map__put in propagate_maps()

Browse source 
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.
