zfs: add missing checks for unsupported features

After the merge of OpenZFS master-9312e0fd1 it has become possible to
import ZFS pools witn an active org.illumos:edonr feature on FreeBSD,
leading to a panic.

In addition, "zpool status" reported all pools without edonr as upgradable
and "zpool upgrade -v" lists edonr in the list of upgradable features.

This is an accepted but not yet included bugfix by upstream.
