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.
