[PULL,03/13] docs/qapidoc: delint a tiny portion of the module

Commit Message

From: John Snow <[e-mail]>

In a forthcoming series that adds a new QMP documentation generator, it
will be helpful to have a linting baseline. However, there's no need to
shuffle around the deck chairs too much, because most of this code will
be removed once that new qapidoc generator (the "transmogrifier") is in
place.

To ease my pain: just turn off the black auto-formatter for most, but
not all, of qapidoc.py. This will help ensure that *new* code follows a
coding standard without bothering too much with cleaning up the existing
code.

Code that I intend to keep is still subject to the delinting beam.
