Alexander Graf 131fe64e63 hw/virtio/virtio-nsm: Respond with correct length 
When we return a response packet from NSM, we need to indicate its
length according to the content of the response. Prior to this patch, we
returned the length of the source buffer, which may confuse guest code
that relies on the response size.

Fix it by returning the response payload size instead.
