    As no md personalities honour the merge_bvec_fn of underlying devices,
    we must make sure never to submit a bio larger than 1 page when a 
    merge_bvec_fn is defined.
    
    raid5 already does this (it never submits bios larger than one page).
    With this patch, all other raid personalities limit their
    max_sectors when a merge_bvec_fn is present.
