.. and other related fields that do not need to be enabled
for events that have sampling leader.
It fixes the perf top usage Ingo reported broken:
# perf top -e '{cycles,msr/aperf/}:S'
The 'msr/aperf/' event is configured for write_back sampling, which is
not allowed by the MSR PMU, so it fails to create the event.
Adjusting related attr test.
