cciss: fix scatter gather chain block dma direction kludge
The data direction for the chained block of scatter gather
elements should always be PCI_DMA_TODEVICE, but was mistakenly
set to the direction of the data transfer, then a kludge to
fix it was added, in which pci_dma_sync_single_for_device or
pci_dma_sync_single_for_cpu was called. If the correct direction
is used in the first place, the kludge isn't needed.
