[PATCH v2 1/2] Revert "scsi: aacraid: Remove reference to Series-9"

This reverts commit 395e5df79a9588abf1099ea746f11872c9086252.

The patch being reverted not only drops Series-9 cards
checks but also changes logic for Series-6 controllers which
lead to controller hungs/resets under high io load.

So revert the original patch, references to Series 9 are to
be removed by next patch.
