Because the only caller of the alloc_event()
(pevent_parse_event) checks return value properly,
it can be changed to use plain malloc.

Perhaps we should combined these to:

{
	struct event_format *event;

	event = calloc(1, sizeof(*event));
	return event;
}

Or even:

{
	return calloc(1, sizeof(struct event_format));
}

tools lib traceevent: Replace malloc_or_die to plain malloc in alloc_event()
