Floss: Fix regression of no scan results

Refactor in aosp/2470982 adds more restriction when ignoring scan
response: only for Android HCI extension should ignore scan response.
But actually the hardware filter is also used with non-Android HCI
extension, e.g. MSFT extension. Therefore we should relax the condition
to be not restricted to Android HCI scan mode only, just like prior to
the refactor.
