xen/netfront: read response from backend only once
commit 8446066bf8c1f9f7b7412c43fbea0fb87464d75b upstream.
In order to avoid problems in case the backend is modifying a response
on the ring page while the frontend has already seen it, just read the
response into a local buffer in one go and then operate on that buffer
only.
