block/badblocks: fix the bug of reverse order

hulk inclusion
category: bugfix
bugzilla: 188569, https://gitee.com/openeuler/kernel/issues/I6ZG5B
CVE: NA

--------------------------------

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
    1536 512
    1024 512
    512 512
    0 512
