KAFKA-4557: Handle Producer.send correctly in expiry callbacks
When iterating deque for expiring record batches, delay the actual
completion of the batch until iteration is complete since callbacks invoked
during expiry may send more records, modifying the deque, resulting in
ConcurrentModificationException in the iterator.
