[network-manager-applet: 1/3] wifi-dialog: remember the specific_connection construct parameter

[Beniamino Galvani <bgalvani src gnome org>]

commit 348cc284bf3497dcef6394e8438a9c4a8411852e

    wifi-dialog: remember the specific_connection construct parameter
    
    The specific_connection parameter is passed to
    connection_combo_init(), which stores the connection in
    priv->connection. When the user changes device, device_combo_changed()
    calls again connection_combo_init() passing a NULL argument and so the
    specific connection gets lost.
    
    Store the specific_connection in the dialog private data and use it
    when the connection combo is re-initialized.
