perf tools: Fix error index for pmu event parser

Browse Source 
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?
