[PATCH 1/2] f2fs: don't skip checkpoint if there is no dirty node pages

[Jaegeuk Kim]

This is the errorneous scenario.
1. write data
2. do checkpoint
3. produce some dirty node pages by the gc thread
4. write back dirty node pages
5. f2fs_put_super will skip the checkpoint, since dirty count for node pages is
  zero.

This patch removes such the wrong condition check.
