Subject: [PATCH 2/4] Bluetooth: Fix: LL PRivacy BLE device fails to connect
When adding device to white list the device is added to resolving list
also. It has to be added only when HCI_ENABLE_LL_PRIVACY flag is set.
HCI_ENABLE_LL_PRIVACY flag has to be tested before adding/deleting devices
to resolving list. use_ll_privacy macro is used only to check if controller
supports LL_Privacy.

Fixes: 0eee35bdfa3b ("Bluetooth: Update resolving list when updating whitelist")
