Bluetooth: Correct the max sdu length used from BT-IF layer
- Correct the max sdu length used from BT-IF layer to be in
sync with max sdu calculation from L2cap layer.
- max sdu of l2cap layer will be communicated to the upper
layers, and same length of sdu being sent from upper layer
to BT-IF layer, but because of change in the max sdu of
BT-IF, it will receive less bytes than expected will lead
to form incomplete PUT request.
