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

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.
