perf ftrace: Fix leak in parse_filter_event

strsep() advances the pointer given to it. After the loop s is
either NULL (on success) or points mid buffer (early exit if malloc
fails) so the original buffer is never freed properly.
Fix by adding a tmp pointer for use by strsep and free the original
pointer
