The attached sample code compiled as
nvcc -std=c++11 -o cub_bug cub_bug.cu

with cub 1.7.4 results in incorrect count for the last element

Mismatching count for key 130882: 1 vs. 2

          Fix for Issue#127: (DeviceRunLengthEncode::Encode returns wrong results)

https://github.com/NVlabs/cub/issues/127 

Applied reduction-op instead of RLE-scan-op for last item, so was always
(insead of conditionally) folding in the last block's prefix count.
