[PATCH 13/19] qapi: Eliminate .check_doc() overrides

[Markus Armbruster <armbru@redhat.com>]

All sub-classes of QAPISchemaEntity now override .check_doc() the same
way, except for QAPISchemaType and and QAPISchemaArrayType.

Put the overrides' code in QAPISchemaEntity.check_doc(), and drop the
overrides.  QAPISchemaType doesn't care because it's abstract.
QAPISchemaArrayType doesn't care because its .doc is always None.
