[PATCH 05/12] perf tools: Fix error index for pmu event parser

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jo...@kernel.org>

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?
