I don't think the Daedra have any claim over the DB's soul. Herma Mora took Miraak just before he was about to die and granted him Immortality. Had he not done this, Miraak's dragon soul would have been free to go to Sovngarde. Tsun even states that you will let into Sovngarde whether or not you've pledged yourself to Sithis or  Nocturnal. He always states that at your end of days you can go to Sovrngarde. That or it seems if you kill another Dragonborn like Miraak or if he were to kill you. He'd absorb your soul the way you do him. I don't think a Dragon Soul is like a normal soul at all. It seems more like a divine soul that not even the Daedra can claim.
