thunderbolt: Restart XDomain discovery handshake after failure
Alex reported that after rebooting the other host the peer-to-peer link does not come up anymore. The reason for this is that the host that was not rebooted tries to send the UUID request only 10 times according to the USB4 Inter-Domain spec and gives up if it does not get reply. Then when the other side is actually ready it cannot get the link established anymore. The USB4 Inter-Domain spec requires that the discovery protocol is restarted in that case so implement this now.
