Ding Tianhong a6a5993243 iov_iter: don't revert iov buffer if csum error
The patch 3278682123 (make skb_copy_datagram_msg() et.al. preserve
->msg_iter on error) will revert the iov buffer if copy to iter
failed, but it didn't copy any datagram if the skb_checksum_complete
error, so no need to revert any data at this place.

v2: Sabrina notice that return -EFAULT when checksum error is not correct
    here, it would confuse the caller about the return value, so fix it.

Fixes: 3278682123 ("make skb_copy_datagram_msg() et.al. preserve->msg_iter on error")
