[PATCH 2/7] perf stat: Remove unused default_null_attrs

[James Clark]

All current implementations of arch_evlist__add_default_attrs() do
nothing if nr_attrs is 0. To avoid confusion that it's used, remove it.

It appears that it used to be used as a mechanism to add topdown events,
but this is now done separately.
