Remove the SCSI pointer from struct scsi_cmnd

Hi Martin, The size of struct scsi_cmnd matters for embedded devices. One of the largest members of that structure is the SCSI pointer. That structure is only relevant for SCSI-II drivers but not for modern SCSI drivers. Hence this patch series that removes the SCSI pointer from struct scsi_cmnd. Please consider this patch series for kernel v5.18. Thanks, Bart.
