The code as written crashes when a free-form documentation block doesn't
start with a heading or subheading, for example:
| ##
| # Just text, no heading.
| ##
The code will attempt to use the `node` variable uninitialized. To fix,
create a generic block to insert the doc text into.
(This patch also removes a lingering pylint warning in the QAPIDoc
implementation that prevents getting a clean baseline to use for
forthcoming additions.)
Fixes: 43e0d14ee09a (docs/sphinx: fix extra stuff in TOC after freeform QMP sections)

Not worth a respin by itself.
