[PATCH 1/2] mtd: nand: sunxi: fix sunxi_nfc_hw_ecc_read/write_chunk()

[Boris Brezillon]

The sunxi_nfc_hw_ecc_read/write_chunk() functions try to avoid changing
the column address if unnecessary, but the logic to determine whether it's
necessary or not is currently wrong: it adds the ecc->bytes value to the
current offset where it should actually add ecc->size.
