From: Li Nan <linan122@xxxxxxxxxx>
Order of badblocks will be reversed if we set a large area at once. 'hi'
remains unchanged while adding continuous badblocks is wrong, the next
setting is greater than 'hi', it should be added to the next position.
Let 'hi' +1 each cycle.
# echo 0 2048 > bad_blocks
# cat bad_blocks
