Revert "net: add length argument to skb_copy_and_csum_datagram_iovec"
This reverts commit 127500d724f8c43f452610c9080444eedb5eaa6c. That fixed
the problem of buffer over-reads introduced by backporting commit
89c22d8c3b27 ("net: Fix skb csum races when peeking"), but resulted in
incorrect checksumming for short reads. It will be replaced with a
complete fix.
