vhost-net-user: add stubs for when no virtio-net device is present
hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the vhost-user code is always compiled into QEMU, only the constructor net_init_vhost_user is unreachable. Also, net/vhost-user.c needs functions declared in hw/virtio/vhost-stub.c even if no virtio device exists. Break this dependency. First, add a minimal version of net/vhost-user.c, with no functionality and no dependency on vhost code. Second, #ifdef out the calls back to net/vhost-user.c from hw/net/vhost_net.c. While at it, this patch fixes the CONFIG_VHOST_NET_USE*D* typo.
