Ian Rogers da86f80da3 perf stat: Clear evsel->reset_group for each stat run ...

commit bf515f024e4c0ca46a1b08c4f31860c01781d8a5 upstream.

If a weak group is broken then the reset_group flag remains set for
the next run. Having reset_group set means the counter isn't created
and ultimately a segfault.

A simple reproduction of this is:

  # perf stat -r2 -e '{cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles}:W

which will be added as a test in the next patch.

Fixes: 4804e01116 ("perf stat: Use affinity for opening events")
