perf report: Fix regression when decoding intel_pt traces
Commit (93d10af26bb7 perf tools: Optimize sample parsing for ordered events) breaks intelPT trace decoding by invariably returning an error if the event type isn't a PERF_SAMPLE_TIME. With this patch the timestamp is initialised and processing is allowed to continue if the error returned by function perf_evlist__parse_sample_timestamp() is not a fault.
