perf session: Remove sample_type_check from event_ops
This is really something tools need to do before asking for the
events to be processed, leaving perf_session__process_events to
do just that, process events.
Also add a msg parameter to perf_session__has_traces() so that
the right message can be printed, fixing a regression added by
me in the previous cset (right timechart message) and also
fixing 'perf kmem', that was not asking if 'perf kmem record'
was ran.
