Remove a hack in the sg driver that alters the total buffer
length for SG_IO commands to ensure buffers are not odd byte
lengths. This breaks on the ipr driver since it requires the
request_bufflen to equal the length specified in the cdb.
The block layer SG_IO code does not appear to have this hack.
