When no events or PMUs match report an error for event_pmu:

Before:
```
$ perf stat -e 'asdfasdf' -a sleep 1
Run 'perf list' for a list of valid events

 Usage: perf stat [<options>] [<command>]

    -e, --event <event>   event selector. use 'perf list' to list available events
```

After:
```
$ perf stat -e 'asdfasdf' -a sleep 1
event syntax error: 'asdfasdf'
                     \___ Bad event name

Unabled to find PMU or event on a PMU of 'asdfasdf'
Run 'perf list' for a list of valid events

 Usage: perf stat [<options>] [<command>]

    -e, --event <event>   event selector. use 'perf list' to list available events
```

Fixes the inadvertent removal when hybrid parsing was modified.
