[PATCH 05/20] qapi/parser: adjust info location for doc body section

[John Snow]

Instead of using the info object for the doc block as a whole, update
the info pointer for each call to ensure_untagged_section when the
existing section is otherwise empty. This way, Sphinx error information
will match precisely to where the text actually starts.
