Subject: [PATCH] perf stat: Clear evsel->reset_group for each stat run

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.
