Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page. Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature. All drivers not setting
use_clustering at all are switched to set DISABLE_CLUSTERING to keep
the current behavior.
