An interface can be disabled while it has an ongoing scan request. In such a case, when the scan results notification is received it is being ignored (as the interface is already disabled) so the scan state is not cleared. This can cause undetermined behavior for the next scan request. To handle this, clear the scan state when EVENT_SCAN_RESULTS is received and the interface is disabled.
