[Yaffs] Older yaffs bad block detection

We were having some issues with a ~4 month old yaffs checkout, where it
would incorrectly think that blocks were bad. It appeared as though it
was using MTD_OOB_AUTO to read the OOB tags, but then assuming that byte
5 of these contained the bad block marker. This was all before the large
patch which added yaffs_mtdif1.c. Has anyone seen this issue in older
versions - was it a known bug?

We've updated to the latest version, and the problem appears to have
gone away, but I'd just like to be sure.
