perf annotate-data: Fix a buffer overflow in TUI browser
In get_member_overhead(), k is updated when it has a entry in the
histogram. But the entry->hists array is allocated with the number of
evsel in the group. So the k should be reset when it iterates the event
using for_each_group_evsel(), otherwise it'd crash due to a buffer
overflow.
