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 we do not
need to do anything (drop the references) for not implemented yet
TX_CLONE_RANGE replay for ZVOLs.
This is a logical follow up to #15603.
