zil_claim_clone_range() takes references on cloned blocks before ZIL replay. Later zil_free_clone_range() drops them after replay or on dataset destroy. The total balance is neutral. It means on actual replay we must take additional references, which would stay in BRT. Without this blocks could be freed prematurely when either original file or its clone are destroyed. I've observed BRT being emptied and the feature being deactivated after ZIL replay completion, which should not have happened. With the patch I see expected stats.
