When an incoming SCO connection is requested, check the selected mode, and
reply appropriately. Mode should have been negotiated previously. For example,
in case of HFP, the codec is negotiated using AT commands on the RFCOMM
channel. This patch only changes replies for socket with defered setup enabled.
