Bluetooth: Remove l2cap_conn->src and l2cap_conn->dst usage from L2CAP
The l2cap_conn->src and l2cap_conn->dst addresses are just a pointers to hci_conn structure. Use hci_conn->hdev->bdaddr and hci_conn->dst directly instead. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
