[SCSI] sym53c8xx: Remove data_mapping and data_mapped
Before all commands used sg, data_mapping and data_mapped were used to
distinguish whether the command had used map_single or map_sg. Now all
commands are sg, so we can delete data_mapping, data_mapped and the
wrapper functions __unmap_scsi_data, __map_scsi_sg_data, unmap_scsi_data
and map_scsi_sg_data.
