    wayland/inhibit-shortcuts-dialog: Just hide the dialog when hiding
    
    The meta_wayland_surface_hide_inhibit_shortcuts_dialog() function
    disconnected the "destroy" handler, but we'd still be listening on
    response events. Change this to just hide the dialog, leaving the data
    intact with the proper life time signal in place.
