Our array nand_ecc_algos doesn't specify mappings for all available
enum nand_ecc_algo values. The one missing there is NAND_ECC_UNKNOWN
as this value is reserved for algorithm not being specified at all.
It means we have to be careful when iterating this array and avoid
NULL values.

V2: Iterate from NAND_ECC_HAMMING instead of checking for NULL as preferred by
Boris.
