iov_iter: don't revert iov buffer if csum error
The patch 327868212381 (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: 327868212381 ("make skb_copy_datagram_msg() et.al. preserve->msg_iter on error")
