[SCSI] Add SUN Universal Xport to no attach blacklist
I was using a Sun ST2510 device (iSCSI) and a special "block device"
appeared which is used by SUN Common Array Manager in-band management.
However it also appeared as a block device and caused some IO error:
[ 716.868000] scsi 15:0:0:31: Direct-Access SUN Universal Xport 0735 PQ: 0 ANSI: 5

After some googling it appeared that similar issue has been solved for
SGI/IBM devices in 4869040512082b761de2d7c35975d01044f8bfea, so here is
the patch for SUN, please apply.
