Bluetooth: Ignore BR/EDR packet size constraints when fragmenting for AMP

Browse source 
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.
