[PATCH] perf stat: Ensure group is defined on top of the same cpu mask

Jin Yao reported the issue (and posted first versions of this change) with groups being defined over events with different cpu mask. This causes assert aborts in get_group_fd, like: # perf stat -M "C2_Pkg_Residency" -a -- sleep 1 perf: util/evsel.c:1464: get_group_fd: Assertion `!(fd == -1)'
