This reverts commit 66110abc4c931f879d70e83e1281f891699364bf.
If we clear the cold data flag out of the writeback flow, we can miscount
-1 by end_io.
Balancing F2FS Async:
- IO (CP: 1, Data: -1, Flush: ( 0 0 1), Discard: ( ...
GC thread: IRQ
- move_data_page()
- set_page_dirty()
- clear_cold_data()
- f2fs_write_end_io()
- type = WB_DATA_TYPE(page);
here, we get wrong type
- dec_page_count(sbi, type);
- f2fs_wait_on_page_writeback()
