Subject: [PATCH 24/33] perf, tools: Move parse_events error printing to parse_events_options

From: Andi Kleen <ak@...ux.intel.com>

The callers of parse_events usually have their own error handling.
Move the fprintf for a bad event to parse_events_options, which
is the only one who should need it.
