id
This function can be called by anyone. In this function, any remaining collateral after liquidation of the loan with the given id is sent to its borrower. Note: The loan is liquidated during the auction period after the expiry of the corresponding loan market. Since the auction is active until either all FUnderlying has been sold or the required currency amount has been raised, this function will work only after the auction is closed, aka, the corresponding loan market has been settled.
