perf probe: Reject second attempt of adding same-name event
Reject second attempt of adding same-name event. This patch
also provides --force option which allows user to add additional
probe events on the same-name event.
e.g.
(the first attempt : success)
./perf probe schedule
Added new event:
probe:schedule (on schedule+0)
(the second attempt : failure)
./perf probe schedule:11
Error: event "schedule" already exists. (Use -f to force duplicates.)
Fatal: Can't add new event.
(the second attempt with -f : successfully added)
./perf probe -f schedule:11
Added new event:
probe:schedule_1 (on schedule+45)
