perf session: Skip event correctly for unknown id/machine
In case the perf_session__process_event function fails, we estimate the next event offset. This is not necessary for sample event failing on unknown ID or machine. In such case we know proper size of the event, so we dont need to guess. Also failure statistics are updated correctly so we don't miss any information. Forcing perf_session__process_event to return 0 in case of unknown ID or machine.
