Address resolution will be paused during active scan to allow any
advertising reports reach the host. If LL privacy is enabled,
advertising will rely on the controller to generate new RPA.
If host is not using RPA, there is no need to stop advertising during
active scan because there is no need to generate RPA in the controller.
