    gsocketaddress: Add an assertion to help static analysis
    
    The static analyser will check dynamic type assertions and assume that
    if they fail, the variable can either have the wrong type, or be NULL
    (which is correct). The analyser doesn’t know that other constraints in
    the API ensure the variable is non-NULL.
    
    Add a non-null assertion to help the static analyser and shut it up in
    this case.
