This also fixes a bug with specific (position specified) queries on keyless
lists. If the `get_next` callback is using the parent entry it will probably
crash as the code is passing the list_entry as both parent and child in the
specific lookup case.
There may currently be no code that uses the parent entry if the child entry is
non-NULL, though.

The code doesn't push more than one group (currently) so wouldn't hit the
bug yet, nice catch by coverity.
