Chao Yu 7bcd0cfa73 f2fs: don't trigger data flush in foreground operation 
Data flush can generate heavy IO and cause long latency during
flush, so it's not appropriate to trigger it in foreground
operation.

And also, we may face below potential deadlock during data flush:
- f2fs_write_multi_pages
 - f2fs_write_raw_pages
  - f2fs_write_single_data_page
   - f2fs_balance_fs
    - f2fs_balance_fs_bg
     - f2fs_sync_dirty_inodes
      - filemap_fdatawrite   -- stuck on flush same cluster
