In forced flush (OE_FLUSH__HALF) we break the rules of the flush
timestamp via PERF_RECORD_FINISHED_ROUND event, so we could get out of
order event.
Do not force error in this case plus changing the output warning to use
WARN_ONCE.

Adding some prints for ordered events queue, to help debug issues.
Adding debug_ordered_events debug variable to be able to enable ordered
events debug messages using:
$ perf --debug ordered-events=2 report ...
Also using oe pointer in perf_session__queue_event instead of chained
session variable dereferencing.
