Stéphane Lesimple 4fc1ea9c6c zpool: fix redundancy check after vdev removal
The presence of indirect vdevs was confusing get_redundancy(), which
considered a pool with e.g. only mirror top-level vdevs and at least
one indirect vdev (due to the removal of a previous vdev) as already
having a broken redundancy, which is not the case. This lead to the
possibility of compromising the redundancy of a pool by adding
mismatched vdevs without requiring the use of `-f`, and with no
visible notice or warning.
