Subject: [PATCH 11/13] perf tools: Rename parse_events__free_terms() to parse_events_terms__delete()

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To follow convention used in other tools/perf/ areas. Also remove the
need to check if it is NULL before calling the destructor, again, to
follow convention that goes back to free().
