[ARM] ARM SCSI: Don't try to dma_map_sg too many scatterlist entries
An off-by-one bug meant we were always trying to map one too many
scatterlist entries. This was mostly harmless prior to the checks
going in to consistent_sync(), but now causes the kernel to BUG.
Also, powertec.c was missing an assignment to info->ec.
