    mtd: initialize writebufsize in the MTD object of a partition
    
    Propagate the writebufsize to the partition's MTD object so
    that UBI can set correct value for it's minimal I/O size
    using the writebufsize field of MTD object of the partition.
    
    By previous patches we added proper writebufsize field
    initialization. Next patch can now change UBI to use
    this field for setting the minimal I/O size.
