Ruling from Gatherer:"If Fiend Hunter leaves the battlefield before its first ability has resolved, its second ability will trigger and do nothing. Then its first ability will resolve and exile the targeted creature indefinitely."

Fiend Hunter+Nantuko Husk is not a perma exile. Fiend hunter reads when ~ leaves the battlefield, return exiled permanent under its owner's control. This means when you sac it to nantuko, it leaves the battlefield and the card is returned.
