From: Shida Zhang <zhangshida@xxxxxxxxxx>
This kinda revert the commit 56d35a4cd13e("ext4: Fix dirtying of
journalled buffers in data=journal mode") made by Jan 14 years ago.
Now that the whole __block_write_begin and improperly dirty things
were removed from the code. Remove the related code, too.
Now we get a better and cleaner world!
