Crash 'Call' object has no attribute 'name' when accessing a private class variable

[bugale]

Bug description

Seems similar to #4638, but reproduces after its fix

When parsing the following file:

class A:
    @classmethod
    def b(cls) -> None:
        cls.__a = ''

    def a(self):
        type(self).__a

pylint crashed with a AttributeError and with the following stacktrace:
