[PATCH v2 12/19] qapi/schema: assert info is present when necessary

[John Snow <jsnow@redhat.com>]

QAPISchemaInfo instances are sometimes defined as an Optional
field/argument because built-in definitions don't *have* a source
definition. As a consequence, there are a few places where we need to
assert that it's present because the root entity definition can only
enforce that it is "Optional".
