    mtd: nand: Use the mirror BBT descriptor when reading its version
    
    The code responsible for reading the version of the mirror bbt was
    incorrectly using the descriptor of the main bbt.
    
    Pass the mirror bbt descriptor to 'scan_read_raw' when reading the
    version of the mirror bbt.
