perf tools: Do not zero sample_id_all for group members
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.
