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.
