Live migration of virtio-fs is still at the early discussion stage AFAICT.
It might take time before we have something working. But in the meantime,
it seems abusive to block migration if we have a guarantee that the device
isn't servicing requests. FWIW virtio-9p only blocks migration when the
shared directory is mounted on the guest.
