Adrian Hunter 129fe9d509 perf parse-events: Fix segfault when event parser gets an error 
commit 2e828582b8 upstream.

parse_events() is often called with parse_events_error set to NULL.
Make parse_events_error__handle() not segfault in that case.

A subsequent patch changes to avoid passing NULL in the first place.

Fixes: 43eb05d066 ("perf tests: Support 'Track with sched_switch' test for hybrid")
