Going up to the first-level tree to continue search there.
Only done when performing prefix search.
Key buffer data pointer as well as docid[0] may be smaller
than values we got while searching first-level tree. Thus
they must be restored to original values to avoid dead-loop,
when subsequent search for a bigger value eventually ends up
in this same second-level tree.
