[PATCH] perf tools: Do not zero sample_id_all for group members

[Jiri Olsa <jolsa@kernel.org>]

Andi reported following malfunction:

  # perf record -e '{ref-cycles,cycles}:S' -a sleep 1
  # perf script
  non matching sample_id_all

That's because we disable sample_id_all bit for non-sampling
group members. We can't do that, because it needs to be the
same over the whole event list. This patch keeps it untouched
again.

Fixes: e9add8bac6c6 ("perf evsel: Disable write_backward for leader sampling group events")
