Indicate scan completion in active AP mode even when ignoring results

Indicate scan completion in active AP mode even when ignoring results

This is needed to avoid leaving external components (through control
interface or D-Bus) timing out while waiting for the scan completion
events. This was already taken care of for the scan-only case
("TYPE=only"), but the scan-and-allow-roaming case did not report the
scan completion event when operating in AP mode.
