[PATCH] Set max_sectors for raid0 only, not for all raid levels.
raid1 and multipath have not concept of a chunksize, so basing
max_sectors on it is obviously wrong.
Similary 'linear' has a very different concept of chunksize and
max_sectors doesn't apply.
raid5 does have relevant chunk_size concept, but it has code to
effectively handle any chunksize.
So we only need to set max_sectors based on chunk_size in raid0.
