Fix reboot logic.  An indentation error meant that every second reboot would
be refused, with the domain being destroyed instead.

Further fix for reboot logic when using on_reboot=rename-restart: the incorrect
node was being removed once restart has completed, leaving Xend to conclude
later that it had crashed in the middle of a restart.
