net: Introduce skb_copy_datagram_from_iter_full()
In a similar manner to copy_from_iter()/copy_from_iter_full(), introduce
skb_copy_datagram_from_iter_full() which reverts the iterator to its
initial state when returning an error.
A subsequent fix for a vsock regression will make use of this new
function.
