perf report: Output non-zero offset for decompressed records
Print offset of PERF_RECORD_COMPRESSED record instead of zero for
decompressed records in raw trace dump (-D option of perf-report):
0x17cf08 [0x28]: event: 9
instead of:
0 [0x28]: event: 9
The fix is not critical, because currently file_pos for compressed
events is used in perf_session__process_event only to show offsets
in the raw dump.
This patch was separated from patchset:
https://lore.kernel.org/lkml/cover.1629186429.git.alexey.v.bayduraev@linux.intel.com/
and was already rewieved.
