From: Shmulik Ladkani <shmulik.ladkani@gmail.com>

commit 7bb9c75436212813b38700c34df4bbb6eb82debe upstream.

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.
