f2fs: should not truncate blocks during roll-forward recovery

If the file preallocated blocks and fsync'ed, we should not truncate them during roll-forward recovery which will recover i_size correctly back. Fixes: d4dd19e ("f2fs: do not expose unwritten blocks to user by DIO") Cc: <[email protected]> # 5.17+ Signed-off-by: Jaegeuk Kim <[email protected]>
