[MTD NAND] Reduce paranoia level when scanning for bad blocks on virgin chips
We were scanning for 0xFF through the entire chip -- which takes a while when it's a 512MiB device as I have on my current toy. The specs only say we need to check certain bytes -- so do only that. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
