    xen/netback: do not attempt to connect in the Initialised state
    
    Only attempt to fetch the configuration data and connect the shared
    ring once the frontend has switched to the 'Connected' state. This
    seems to be inline with what Linux netback does, and is required to
    make newer versions of NetBSD netfront work, since NetBSD only
    publishes the required configuration before switching to the Connected
    state.
