Namhyung Kim b314e5cfd1 perf session: Fix infinite loop on invalid perf.data file ... perf-record updates the header in the perf.data file at termination. Without this update perf-report (and other processing built-ins) it caused an infinite loop when perf report (or something like) called. This is because the algorithm in __perf_session__process_events() depends on the data_size which is read from file header. Use file size directly instead in this case to do the best-effort processing.
