[SCSI] aacraid: regression fix
The fixes for sparse warnings mixed in with the fixups for the raw_srb handler resulted in a bug that showed up in the 32 bit environments when trying to issue calls directly to the physical devices that are part of the arrays (ioctl scsi passthrough). Received from Mark Salyzyn at adaptec. Applied comment from Christoph to remove cpu_to_le32(0) Applied Mark S fix of missing memcpy. It applies to the scsi-misc-2.6 git tree.
