ENGR00132026 MTD: Fix MTD_MODE_RAW write fail
Kobs-ng use MTD_MODE_RAW write boot stream to NAND flash.
mtdchar have not initilized all field of struct mtd_oob_ops
in mtd_write when mode is MTD_MODE_RAW.
function nand_do_write_ops
if (ops->ooboffs && (ops->ooboffs + ops->ooblen > oobmaxlen))
return -EINVAL;
ooboffs is not initilized at mtd_write.
So random data cause nand_do_write_ops return fail.
