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. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
