From: John Snow <jsnow@redhat.com>

QAPISchemaInfo arguments can often be None because built-in definitions
don't have such information.  The type hint can only be
Optional[QAPISchemaInfo] then.  But, mypy gets upset about all the
places where we exploit that it can't actually be None there.  Add
assertions that will help mypy over the hump, to enable adding type
hints in a forthcoming commit.
