success_url is unneeded in PasswordView

[Zhenguo Niu]

Since PasswordForm handle success return http.HttpResponseRedirect(settings.LOGOUT_URL), it's no need to set success_url in PasswordView.

    Remove the unused success_url and return

    Since 'Change Password' form handle successfully return
    httpResponseRedirect(settings.LOGOUT_URL), it's no need
    to set success_url and never reach the 'return True' at
    the end.
