[ Upstream commit 1fb17dfc258ff6208f7873cc7b8e40e27515d2d5 ]
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.
