[SCSI] add SCSI_UNKNOWN and LUN transfer limit restrictions
Original From: Ingo Flaschberger <if@xip.at>
To support the RA4100 array from Compaq.
This patch now correctly handles SCSI_UNKNOWN types with regard to
BLIST_REPORTLUNS2 (allow it) and cdb[1] LUN inclusion (don't).
It also allows a BLIST_MAX_512 flag to restrict the maximum transfer
length to 512 blocks (apparently this is an RA4100 problem).
