perf tools: Fix error index for pmu event parser
For events we provide specific error message we need to set error column index, PMU parser is missing that, adding it. Before: $ perf stat -e cycles,krava/cycles/ kill event syntax error: 'cycles,krava/cycles/' \___ Cannot find PMU `krava'. Missing kernel support? After: $ perf stat -e cycles,krava/cycles/ kill event syntax error: 'cycles,krava/cycles/' \___ Cannot find PMU `krava'. Missing kernel support?
