[SCSI] iscsi: Some fixes in preparation for bidirectional support - total_length
- Remove shadow of request length from struct iscsi_cmd_task. - change all users to use scsi_cmnd->request_bufflen directly (With bidi we will use scsi-ml API to retrieve in/out length) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Cc: Roland Dreier <rdreier@cisco.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
