scsi: fix fall out of sg-chaining patch in qlogicpti
Boaz writes: "I've reviewed all patches since Matthew's, and I find one small problem. In the load_cmd() there is a compound loop where the first 4 sg's are set then the rest are set into a memory structure in group of 7 sg's. Well the second 7-group and on is a bug because sg pointer does not advance. This is a fall out from Jens's patch." The reporter, Meelis Roos <mroos@ut.ee>, verified that this patch does indeed fix his problem with qlogicpti. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
