    xen_console: ignore console disconnect events from console/0
    
    The first console has a different location compared to other PV devices
    (console, rather than device/console/0) and doesn't obey the xenstore
    state protocol. We already special case the first console in con_init
    and con_initialise, we should also do it in con_disconnect.
