MFV r252215:
Restore a previous behavior before r251646, where when destructing ZFS snapshot, the ioctl would return ENOENT when it hit any of them in the errlist (the new behavior was only return ENOENT when all returns error). Illumos ZFS issues: 3829 fix for 3740 changed behavior of zfs destroy/hold/release ioctl MFC after: 1 week
