bluetooth_sendto() uses netdev_findbyindex(conn->bc_ldev + 1) to find the Bluetooth network device for an HCI socket. netdev_findbyindex searches by global interface index, but bc_ldev is a 0-based count of Bluetooth devices only — it bears no fixed relationship to the global interface index. If any netdev other than a Bluetooth device is registered before it (e.g. loopback or Ethernet), the Bluetooth device will not be at global index bc_ldev + 1 and the lookup will return NULL or the wrong device. Fix this by replacing netdev_findbyindex with a netdev_foreach walk using a small callback (bluetooth_dev_byidx_callback) that counts only NET_LL_BLUETOOTH devices and returns the bc_ldev-th one, regardless of what else is registered or in what order.
