scsi: core: Remove struct scsi_pointer from struct scsi_cmnd 

Remove struct scsi_pointer from struct scsi_cmnd since the previous patches
removed all users of that member of struct scsi_cmnd. Additionally, reorder
the members of struct scsi_cmnd such that the statement that the field
below can be modified by the SCSI LLD is again correct.
