vhost: clear signalled_used_valid on vhost stop
When vhost device stops, its implementation synchronizes kernel state back to virtio.c so we can continue emulating the device in userspace. This patch ensures that virtio.c's signalled_used_valid flag is reset so that userspace does not suppress guest notifications due to stale signalled_used values.
