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.
