stats: missing dimension in stat_set_simple_counter
A simple counter is a two dimensional array by threads and
counter index. 28017 introduced an error missing the first
dimension.
If a vector is updated at the same time as a client reads,
an invalid pointer my result. This will be caught by the
optimistic locking after copying out the data, but if
following a pointer outside of the stat segment then
the stat client would crash. Add suitable boundary checks
for access to stat memory segment.
