Jiri Olsa 5ad4da4302 perf tools: Fix parse_events_add_pmu caller 
Following commit changed parse_events_add_pmu interface:
  36adec85a8 perf tools: Change parse_events_add_pmu interface

but forgot to change one caller. Because of lessen compilation rules for
the bison parser, the compiler did not warn on that.
