thunderbolt: xdomain: Notify peers after enumeration

Browse Source 
Service drivers may register local XDomain properties while discovery is
still in progress. This can cause the properties changed notification to be
sent before the peer is ready to act on it.

If the peer has already read the local property block before the service
was registered, it may keep using the old property generation and miss the
newly registered service. With ThunderboltIP this can leave the network
service half-discovered after a warm reboot and the login request
eventually times out.

Queue another properties changed notification after the XDomain reaches
ENUMERATED so the peer can re-read the final local properties.
