[PATCH v2 2/2] scsi: aacraid: Remove references to Series-9 (only)

The patch removes references to Series 9 adapters following
395e5df79a95 ("scsi: aacraid: Remove reference to Series-9"),
but doesn't touch Series 6 adapters logic.

Leaving Series 6 adapters untouched avoids controller
hungs/resets under high io load.
