[PATCH 12/13] qga/qapi-schema: Fix guest-set-memory-blocks documentation

[Markus Armbruster <armbru@redhat.com>]

Documentation claims the command can "return NULL".  "NULL" doesn't
exist in JSON.  "null" does, but the command returns lists, and null
isn't.  Correct documentation to "return an empty list".
