[PULL 20/30] qapi/schema: Call QAPIDoc.connect_member() in just one place

[Markus Armbruster]

The .connect_doc() of classes that have QAPISchemaMember connect them
to their documentation.  Change them to delegate the actual work to
new QAPISchemaMember.connect_doc().  Matches the .connect_doc() that
already exist.
