Answer: In the shot at the very end of the spacecraft the Asgardians are on (after we know Loki is OK) we see the ship they stole from the Grand Master docked to the top of it. Loki flew that ship to the vault, presumably landed as close as possible, placed the crown in the eternal fire, and in the brief time it took for the fire demon to grow, had time to escape the vault, get back in the ship, and fly to safety. I thought Thor was assuming Loki would choose to go his own way rather than rejoin the others, and was pleasantly surprised that he decided to come along too.
