The DDT is really inefficient on 4k and up vdevs, because it always allocates 4k blocks, and while compression could save us somewhat at ashift 9, that stops being true. So let's change the default to 32 KiB, which seems like a reasonable compromise between improved space savings and inflated write sizes for DDT updates.
