[PATCH] coverity: i386: scsi_lib buffer overrun fix

The check in

627  		BUG_ON(index > SG_MEMPOOL_NR);

with SG_MEMPOOL_NR defined in

32   	#define SG_MEMPOOL_NR		(sizeof(scsi_sg_pools)/sizeof(struct scsi_host_sg_pool))

was not sufficient.

sgp, set in

629  		sgp = scsi_sg_pools + index;

is dereferenced in

630  		mempool_free(sgl, sgp->pool);
