Jiri Olsa 802c8a61d4 Revert "perf: Do not allow optimized switch for non-cloned events" ...

This reverts commit 1f9a7268c6.

With the fix of the initial state for the cloned event we now correctly
handle the error described in:

  1f9a7268c6 perf: Do not allow optimized switch for non-cloned events

so we can revert it.

I made an automated test for this, but its not suitable for automated
perf tests framework. It needs to be customized for each machine (the
more cpu the higher numbers for GROUPS/WORKERS/BYTES) and it could take
longer time to hit the issue.
