Fix fatal bug in wxGetWindowFromHWND() for radio buttons.
wxGetWindowFromHWND() could crash if it was called for a HWND of a radio
button which was not created by wxWidgets because it blindly dereferenced the
user data associated with the button expecting it to be a pointer to
wxRadioBox and crashed if it was something different. And this actually

radio boxes as values. This ensures that we can always safely check whether
the given HWND is a radio button in one of our radio boxes or not.
