[SCSI] scsi_dh_emc: fix mode select request setup
This patch fixes the request setup code for mode selects. I got the fixes from Hannes Reinecke while trying to hunt down some problems and merged it into one patch. I am sending it because Hannes is busy with other things. The patch fixes: - setting of the length for mode selects. - setting of the data direction for mode select 10.
