    hs-v3: Don't cleanup intro point in has_closed()
    
    The hs_service_intro_circ_has_closed() was removing intro point objects if too
    many retries.
    
    We shouldn't cleanup those objects in that function at all but rather let
    cleanup_intro_points() do its job and clean it properly.
    
    This was causing an issue in #23603.
    
    Furthermore, this moves the logic of remembering failing intro points in the
    cleanup_intro_points() function which should really be the only function to
    know when to cleanup and thus when an introduction point should be remembered
    as a failed one.
    
    Fixes #23603
