Bluetooth: Fix RFCOMM usage of in-kernel L2CAP sockets
The CID value of L2CAP sockets need to be set to zero. All userspace applications do this via memset() on the sockaddr_l2 structure. The RFCOMM implementation uses in-kernel L2CAP sockets and so it has to make sure that l2_cid is set to zero. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
