Instead of calling perf_evsel__apply_filter straight away, so that we can, in the next patches, expand the filter with more conditions before actually calling the ioctl to pass the end result filter to the kernel. Now we need to call perf_evlist__apply_filters() after the filter is completely setup, i.e. do the ioctl calls. The perf_evlist__apply_filters() method was already in place, because that is the model for the other tools that receives filters in the command line: go on setting then in the evsel->filter and only at the end, after parsing the whole command line, apply them. We get, as a bonus, a more expressive message that states which event, if any, failed to have the filter applied to, with an error message stating what happened.
