Fixes Issue #3062 where countByKey would give incorrect results for any n > 128 (block size). When there is more than one block's worth of reduction, multiple reduction iterations occur.
The af_nonzero_t transformation would reset the reduced values back to a non-zero flag (1) instead of the actual count between reduction iterations. This operator is now replaced with the af_add_t operator in consequent iterations.
