Bluetooth: Ignore BR/EDR packet size constraints when fragmenting for AMP
When operating over BR/EDR, ERTM accounts for the maximum over-the-air packet size when setting the PDU size. AMP controllers do not use the same over-the-air packets, so the PDU size should only be based on the HCI MTU of the AMP controller.
