[PATCH v1 4/4] libperf evsel: In exit add missed puts and assert close, etc. were called

[Ian Rogers]

A missed evsel__close before evsel__delete was the source of leaking
perf events due to a hybrid test. Add asserts in debug builds so that
this shouldn't happen in the future. Add puts missing on the cpu map
and thread maps.
