This series fix chances to write incorrect ECC data which may cause
uncorrectable ECC error when reading.

changes since v1:
- separate patches into 2.
- use shift operator with byte access to avoid endianness conversion
problems.
- follow linux coding style.

The patch passed the test of UBIFS file-system read/write on Mediatek's
RFB. The tested driver is checked-out from LEDE OpenWRT project's
upstream driver, which is pretty much same as nand/next branch upstream
driver(git clone https://git.lede-project.org/source.git).

  mtd: nand: fix chances to create incomplete ECC data when writing.
