[Bluetooth] Disable disconnect timer during Simple Pairing
During the Simple Pairing process the HCI disconnect timer must be disabled. The way to do this is by holding a reference count of the HCI connection. The Simple Pairing process on both sides starts with an IO Capabilities Request and ends with Simple Pairing Complete. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
