jffs2_check_oob_empty() check that the whole OOB area contains only 0xff
bytes except for the clean marker area. This is broken on OneNAND as writing
clean marker to OOB area will change ECC bytes.

Also the clean marker is not written properly as only the first oobfree
table element is used. But this is a different issue.
