[SCSI] mpt2sas: fix the incorrect scsi_dma_map error checking
scsi_dma_map() returns -1 if an error occurred (zero means that the
command has no data). So the following current code can't catch an
error:
sges_left = scsi_dma_map(scmd);
if (!sges_left) {
sdev_printk(KERN_ERR, scmd->device, "pci_map_sg"
" failed: request for %d bytes!\n", scsi_bufflen(scmd));
return -ENOMEM;
}
