[SCSI] stex: Small fixes
Some small fixes, including: - add data direction in req_msg because new firmware version may require this (backward compatible) - change internal timeout value - change judgment of type st_vsc1 - blank line handling, etc. Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
