perf stat: Micro-optimize the code: memcpy is only required if no event is selected and !null_run
Set attrs and nr_counters if no event is selected and !null_run. Setting of attrs should depend on number of counters, so we need to memcpy only for sizeof(default_attrs) Also set nr_counters as ARRAY_SIZE(default_attrs) in place of hardcoded value.
