There's a bug in the code that checks to see if a firmware file matches the
running cpu that results in firmware files with an extended signature table
always matching.  Luckily the kernel ends up failing the update so no harm is
done.  The attached patch makes the code always fail if no match is found,
instead of accidentally falling through to the "matched:" label.
