vhost: Add stubs for the migration state transfer interface

Migration state transfer interface is only used by vhost-user-fs,
so the interface needs to be defined only when vhost is built.

But I need to use this interface with virtio-net and vhost is not always
enabled, and to avoid undefined reference error during build, define stub
functions for vhost_supports_device_state(), vhost_save_backend_state() and
vhost_load_backend_state().
