[PATCH v3 3/3] perf stat: Fix metric-only aggregation index 1;115;0c Aggregation index was being computed using the evsel's cpumap which may have a different (typically the same or fewer) entries.

[Ian Rogers <irogers@google.com>]

Before:
```
$ perf stat --metric-only -A -M memory_bandwidth_total -a sleep 1

 Performance counter stats for 'system wide':

       MB/s  memory_bandwidth_total MB/s  memory_bandwidth_total MB/s  memory_bandwidth_total MB/s  memory_bandwidth_total MB/s  memory_bandwidth_total MB/s  memory_bandwidth_total
CPU0                            12.8                           0.0                          12.9                          12.7                           0.0                          12.6

After:
```
$ perf stat --metric-only -A -M memory_bandwidth_total -a sleep 1
