[SCSI] atp870u: fix memory addressing bug
From: Alan Cox <alan@redhat.com> The virt_to_bus() wasn't correctly taken out of this driver. It needs to be able to track both physical and virtual addresses for its prd table. Update the driver to do this with separate tracking entries. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
