[SCSI] sg: increase sglist_len of the sg_scatter_hold structure
unsigned short is too small for sizeof(struct scatterlist) * min(q->max_hw_segments, q->max_phys_segments). This fixes memory leak with 4096 segments since 16 (likely sg size with x86) * 4096 sets sglist_len to zero. This might not happen without sg chaining support.
