[SCSI] wd7000: proper fix for boards without sg support

- code used to set sg_tablesize to zero for board revision
    less than 6. This is no longer supported, therefore I
    use sg_tablesize=1 and open code the sg handling for that case.
  - Get rid of use of SG_NONE which will be removed soon.
