[Bluetooth] Fix reference counting during ACL config stage
The ACL config stage keeps holding a reference count on incoming connections when requesting the extended features. This results in keeping an ACL link up without any users. The problem here is that the Bluetooth specification doesn't define an ownership of the ACL link and thus it can happen that the implementation on the initiator side doesn't care about disconnecting unused links. In this case the acceptor needs to take care of this. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
