[SCSI] qlogicpti: fix sg list traversal error in continuation entries
The current sg list traversal logic for the continuation entries doesn't advance the list pointer once all seven slots are used, so the next continuation entry (if there is one) wrongly begins again at the start of the sg list. Fix by advancing the sg pointer after the for_each_sg().
