f2fs: update i_size when __allocate_data_block
The f2fs_direct_IO uses __allocate_data_block, but inside the allocation path, we should update i_size at the changed time to update its inode page. Otherwise, we can get wrong i_size after roll-forward recovery. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
