Cleanup allocation class selection
- For multilevel gang blocks it seemed possible to fallback from
normal to special class, since they don't have proper object type,
and DMU_OT_NONE is a "metadata".  They should never fallback.
 - Fix possible inversion with zfs_user_indirect_is_special = 0,
when indirects written to normal vdev, while small data to special.
Make small indirect blocks also follow special_small_blocks there.
 - With special_small_blocks now applying to both files and ZVOLs,
make it apply to all non-metadata without extra checks, since there
are no other non-metadata types.
