lightnvm: fix incorrect nr_free_blocks stat

Browse Source 
[ Upstream commit bdded1552085b12d23c9be76147d2e96647a098f ]

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.
