f2fs: fix to mark the checkpointed nat entry correctly
The nat cache entry maintains a status whether it is checkpointed or not. So, if a new cache entry is loaded from the last checkpoint, nat_entry->checkpointed should be true. If the cache entry is modified as being dirty, nat_entry->checkpoint should be false. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
