Subject: [PATCH 09/13] perf tools: Use perf_event_terms__purge() for non-malloced terms

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

In these two cases, a 'perf test' entry and in the PMU code the
list_head is on the stack, so we can't use perf_event__free_terms()
(soon to be renamed to perf_event_terms__delete()), because it will
free the list_head as well.
