perf: Do not get values from disabled counters in group format read
It's possible some of the counters in the group could be
disabled when sampling member of the event group is reading
the rest via PERF_SAMPLE_READ sample type processing. Disabled
counters could then produce wrong numbers.
Fixing that by reading only enabled counters for PERF_SAMPLE_READ
sample type processing.
