bluetooth: Notify connection deletion only for SCO/ESCO links.



When SCO is active , if we create a connection to another remote
device and delete it, then the alternate setting for the ISOC
channel is getting disabled.

THis is a bug in the BTUSB driver which listens for connection
deletion notification for both ACL and SCO.

Hence, even if ACL disconnection happens with a different remote
device, we set the alternate setting of the currently active
ISOC endpoint to '0' which disables the ISOC endpoint.

As a result there are no further SCO data being sent to the
BT controller.
