Inline parse_events_evlist_error that is only used in
parse_events_error. Modify parse_events_error to not report a parser
error unless errors haven't already been reported. Make it clearer
that the latter case only happens for unrecognized input.
Before:
```
$ perf stat -e 'cycles/period=99999999999999999999/' true
event syntax error: 'cycles/period=99999999999999999999/'
\___ parser error
event syntax error: '..les/period=99999999999999999999/'
\___ Bad base 10 number "99999999999999999999"
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
$ perf stat -e 'cycles:xyz' true
event syntax error: 'cycles:xyz'
\___ parser error
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 'cycles/period=99999999999999999999/xyz' true
event syntax error: '..les/period=99999999999999999999/xyz'
\___ Bad base 10 number "99999999999999999999"
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
$ perf stat -e 'cycles:xyz' true
event syntax error: 'cycles:xyz'
\___ Unrecognized input
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
```
