Though not confirmed, Loki's Scepter is stated to hold the Mind Stone. When Volstagg says that it is not wise to have two Infinity Stones in Asgard, he is referring to having both the Tesseract (Space Stone) and the Aether (Reality Stone). Keep in mind that Loki's Scepter is still on Earth (as seen in the mid-credits scene for Captain America: The Winter Soldier) in the hands of Baron Von Stucker and HYDRA. Odin's Staff is merely an Asgardian weapon.
