MOVZXandHinata daa56356c8 [TopK] Barrier the histogram round before the leader publishes arrival ...

In radix_topk's large-path round loop the leader published arrival with no
block barrier after the histogram merge, so a peer CTA could observe an
incomplete histogram. Inherited by earlier releases; fixed below the placement
work so both arms of any comparison carry it.
