[PATCH v2 02/21] qapi: linter fixups

[John Snow <jsnow@redhat.com>]

Fix minor irritants to pylint/flake8 et al.

(Yes, these need to be guarded by the Python tests. That's a work in
progress, a series that's quite likely to follow once I finish this
Sphinx project. Please pardon the temporary irritation.)
