This matches the beadm behavior; generally, we need to keep promoting
until the BE is no longer a clone from a snapshot. This fixes scenarios
where the dataset associated with a BE's origin is itself a clone,
activating the BE previously would promote it to a clone of the origin's
origin.
We could keep using be_get_dataset_props here, except for two
annoyances:
1.) I couldn't find a clean way to just clear an nvlist rather than
having to re-alloc it, and I didn't want to just remove the one prop
we're inspecting out of it.
2.) That's a lot of overhead when all we want to do is fetch the origin
anyways.
Note that this is not a complete fix, but it does fix the majority of
cases; deep BE subordinates are still notably broken, pending a patch
from Christian.
