[PATCH] mtd: nand: Use the mirror BBT descriptor when reading its version

[Shmulik Ladkani]

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.

- Spotted while reviewing BBT code.
- Introduced by 7cba7b1 [mtd: nand: add support for BBT without OOB].
- Looks like a typo.
- Not runtime tested.
- Sebastian, care to take a look and Ack?
