charset="utf-8" MigrationParameters needs to have all of its has_* fields marked as true when used as the return of query_migrate_parameters because the corresponding QMP command has all of its members non-optional by design, despite them being marked as optional in migration.json. Extract this code into a function and make it assert if any field is missing. With this we ensure future changes will not inadvertently leave any parameters missing. Also assert that s->parameters _does not_ have any of its has_* fields set. This structure is internal to the migration code and it should not rely on the QAPI-generate has_* fields. We might want to store migration parameters differently in the future.
