If dlc is removed or stops working for some reason don't load a save that uses it and then save over it after, things from the dlc will be removed and if its a house things kept inside will be removed too. If your on a PC you could spawn a new sword otherwise reload a save before it happened if you can. If your on PC use the command  -

Thats for the mid level version of the sword id's for other versions are on the Dragonbane wiki page.

The sword Dragonbane is not needed to beat Alduin though its the shout Dragonrend you need, the sword is good but not really worth restarting the game just to get it back.
