    iomap: don't increase i_size if it's not a write operation

    Increase i_size in iomap_zero_range() and iomap_unshare_iter() is not
    needed, the caller should handle it. Especially, when truncate partial
    block, we should not increase i_size beyond the new EOF here. It doesn't
    affect xfs and gfs2 now because they set the new file size after zero
    out, it doesn't matter that a transient increase in i_size, but it will
    affect ext4 because it set file size before truncate. So move the i_size
    updating logic to iomap_write_iter().
