Am I missing a reason that you think your reservation would be cancelled?
Perhaps they used an annual free night certificate from the credit card. Regardless if it is already in your account you should be fine. One other thought, if you guaranteed the reservation to the card you're planning on cancelling, you're most likely still okay. To be safe you could call in and update the card used to guarantee your reservation.
