scsi: remove the use_clustering flag
The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers. Note that in many cases the setting might be bogus, but this keeps the status quo. [mkp: fix myrs and myrb] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.
