scsi: dc395x: fix dma API usage in srb_done
[ Upstream commit 3a5bd7021184dec2946f2a4d7a8943f8a5713e52 ]
We can't just transfer ownership to the CPU and then unmap, as this will
break with swiotlb.
Instead unmap the command and sense buffer a little earlier in the I/O
completion handler and get rid of the pci_dma_sync_sg_for_cpu call
entirely.
