Subject: [PATCH 02/25] lightnvm: fix incorrect nr_free_blocks stat

From: Chao Yu <chao2.yu@...sung.com>

When initing bad block list in gennvm_block_bb, once we move bad block
from free_list to bb_list, we should maintain both stat info
nr_free_blocks and nr_bad_blocks. So this patch fixes to add missing
operation related to nr_free_blocks.
