Jiri Olsa f4be073db8 perf: Check permission only for parent tracepoint event 
There's no need to check cloned event's permission once the
parent was already checked.

Also the code is checking 'current' process permissions, which
is not owner process for cloned events, thus could end up with
wrong permission check result.
