====================
vsock/virtio: fix vsockmon tap skb construction

While reviewing the patch posted by Yiqi Sun [1] to fix an issue in
virtio_transport_build_skb(), I discovered another issue related to
the offset and length of the payload to be copied in the new skb.
This was introduced when we did the skb conversion, and fixed by
patch 1.

Patch 2 fixes the issue found by Yiqi Sun in a different way: using
iov_iter_kvec() to properly initialize all the iov_iter fields and
removing the linear vs non-linear split like we alredy do in
vhost-vsock.

It could have been a single patch, but since there were two affected
commits, I decided to keep the fixes separate.
