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. Signed-off-by:

Commit d49e4695 ("perf evsel: Add a backpointer to the evlist a evsel is in") updated perf_evlist__add() but not perf_evlist__splice_list_tail(). This illustrates that it is better if perf_evlist__splice_list_tail() calls perf_evlist__add() instead of duplicating the logic, so do that.

The validation checks that the values that were just assigned, got assigned i.e. the error can't ever happen. Subsequent patches will call this code in places where errors are not being returned. Changing those code paths to return this non-existent error is counter-productive, so just remove it. That in turn results in perf_evlist__set_maps not needing to return an error, but callers aren't checking it either, so remove that too. Signed-off-by:
