[PATCH v1 05/13] perf parse-events: Avoid regrouped warning for wild card events

[Ian Rogers <irogers@xxxxxxxxxx>]

There is logic to avoid printing the regrouping warning for wild card
PMUs, this logic also needs to apply for wild card events.

Before:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1
WARNING: events were regrouped to match PMUs

 Performance counter stats for 'system wide':

          2,979.16 MiB  data_read
            410.26 MiB  data_write

       1.001541923 seconds time elapsed
```
After:
```
$ perf stat -e '{data_read,data_write}' -a sleep 1

 Performance counter stats for 'system wide':

          2,975.94 MiB  data_read
            432.05 MiB  data_write

       1.001119499 seconds time elapsed
```
