vhost-net-vdpa: add stubs for when no virtio-net device is present

Browse Source 
net/vhost-vdpa.c will need functions that are declared in
vhost-shadow-virtqueue.c, that needs functions of virtio-net.c.

Copy the vhost-vdpa-stub.c code so
only the constructor net_init_vhost_vdpa needs to be defined.
