From: Rafał Miłecki <rafal at milecki.pl>

This makes printed info consistent with other kernel messages. After
scanning NAND BBT create_bbt() prints offset of each bad block. This
change makes is easy to verify nand_erase_nand() failure reason.

I noticed this inconsistency while using "flash_erase" tool.
