Subject: scsi: aacraid: Fix 2T+ drives on SmartIOC-2000

From: Dave Carroll <[email protected]>

commit 6c92f7dbf25c36f35320e4ae0b508676410bac04 upstream.

The logic for supporting large drives was previously tied to 4Kn support for SmartIOC-2000. As SmartIOC-2000 does not support volumes using 4Kn drives, use the intended option flag AAC_OPT_NEW_COMM_64 to determine support for volumes greater than 2T.
