Xin LI 00769ce74d MFV r272500:
Don't inherit flags other than DS_FLAG_CI_DATASET and DS_FLAG_INCONSISTENT
when cloning.  This prevents DS_FLAG_DEFER_DESTROY being inherited from a
clone that is marked for deferred destroy, which causes snapshots of the
clone being destroyed when getting a hold or clone.

Illumos issue:
    5150 zfs clone of a defer_destroy snapshot causes strangeness
