Yes, your mother can use adult diaper and perform her hajj. But, if the urine gets into the adult diaper making it impure, then she cannot perform tawaf in this state. In order to perform tawaf she will have to clean the impurity and have wudhu. She can perform other rituals of hajj.
It is alright to perform hajj by debt money, hajj shall be valid.
