This patch fixes service discovery behaviour, when provided uuid filter is empty and HCI_QUIRK_STRICT_DUPLICATE_FILTER is set. Before this patch, empty uuid filter was unable to trigger scan restart, and that caused inconsistent behaviour in applications. Example: two DBus clients call BlueZ, one to find all devices with service abcd, second to find all devices with rssi smaller than -90. Sum of those filters, that is passed to mgmt_service_scan is empty filter, with no rssi or uuids set. That caused kernel not to restart scan when quirk was set. That was inconsistent with what happen when there's only one of those two filters set (scan is restarted and reports devices). To fix that, new variable hdev->discovery.result_filtering was introduced. It can indicate that filtered scan is running, no matter what uuid or rssi filter is set.
