datagram: introduce skb_copy_and_hash_datagram_iter helper
Introduce a helper to copy datagram into an iovec iterator but also update a predefined hash. This is useful for consumers of skb_copy_datagram_iter to also support inflight data digest without having to finish to copy and only then traverse the iovec and calculate the digest hash.
