[5.1.x] Fixed #35477 -- Corrected 'required' errors in auth password set/change forms.

The auth forms using SetPasswordMixin were incorrectly including the
'This field is required.' error when additional validations (e.g.,
overriding `clean_password1`) were performed and failed.
This fix ensures accurate error reporting for password fields.
