commit 76c23c32 upstream.

Fix ECC Correction bug where the byte offset location were double
fliped causing correction routine to toggle the wrong byte location
in the ECC segment. The ndfc_calculate_ecc routine change the order
of getting the ECC code.
        /* The NDFC uses Smart Media (SMC) bytes order */
        ecc_code[0] = p[2];
        ecc_code[1] = p[1];
        ecc_code[2] = p[3];
But in the Correction algorithm when calculating the byte offset
location, the b1 is used as the upper part of the address. Which
again reverse the order making the final byte offset address
location incorrect.
	byte_addr = (addressbits[b1] << 4) + addressbits[b0];
The order is change to read it in straight and let the correction
function to revert it to SMC order.
