    qemu-xen: ignore console disconnect events for 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.
    
    This patch should be applied to 4.1 too.

    (cherry picked from commit 2503d4d5a29e7af8dffd1e11229e11c1917d2ccf)
