The function checks, if a bad block table(s) is/are already
available. If not it scans the device for manufacturer
marked good / bad blocks and writes the bad block table(s) to
the selected place.
</p><p>
The bad block table memory is allocated here. It must be freed
by calling the nand_free_bbt function.
