Review Comment:
If the driver doesn't set the markbad and isbad, and the BBM is true, there
will be no crash; those pointers default to NULL, and there is a check before
calling them.
And this is also a valid configuration on a system with multiple MTD drivers
(e.g. one nand using bbm, and another sd card not using that).
