Missing curr_items(1K) after rebalance out on cluster

Test to repro:
./testrunner -i b/resources/your.ini -t rebalance.rebalanceout.RebalanceOutTests.rebalance_out_with_ops,nodes_out=3,replicas=3,items=100000,doc_ops=create:update:delete,max_verify=100000,value_size=1024,dgm_run=true,eviction_policy=fullEviction,active_resident_threshold=90

Test fails on verification of curr_items.
