r8896: Handle more complex case where field being changed doesn't appear

alone in any of userinfo levels. What's needed is extra query step
to fill the userinfo structure and then modify a single field.
The other way to do it is userinfo level 21 with bitmap flags set,
but first all field flags need to be found.
