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.
