Fix bug that cursor position will change when enter newly registered HII Form after ConnectAll() in DeviceManager.
Root cause is that in old code, reinstall of HII handle for DeviceManager will cause inconsistent HII handle index for newly installed HII packages by ConnectAll(), thus cause inconsistent QuestionId. FormBrowser will record QuestionId of a Form ever visited, so the cursor position is changed.
