[PATCH v2 1/5] tools lib traceevent: Replace malloc_or_die to plain calloc in alloc_event()

[Namhyung Kim]

From: Namhyung Kim <namhyung.kim@xxxxxxx>

Because the only caller of the alloc_event()
(pevent_parse_event) checks return value properly
and all it does after allocation is initializing,
it can be changed to use plain calloc.

Thanks to Steven for suggesting this simpler way.
