[NET]: Do not dereference iov if length is zero When msg_iovlen is zero we shouldn't try to dereference msg_iov. Right now the only thing that tries to do so is skb_copy_and_csum_datagram_iovec. Since the total length should also be zero if msg_iovlen is zero, it's sufficient to check the total length there and simply return if it's zero.
