[Bluetooth] Track status of Simple Pairing mode
The Simple Pairing feature is optional and needs to be enabled by the host stack first. The Linux kernel relies on the Bluetooth daemon to either enable or disable it, but at any time it needs to know the current state of the Simple Pairing mode. So track any changes made by external entities and store the current mode in the HCI device structure. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
