8641 "zpool clear" and "zinject" don't work on "spare" or "replacing" vdevs

illumos/illumos-gate@2ba5f978a4

https://www.illumos.org/issues/8641:
"zpool clear" and "zinject -d" can both operate on specific vdevs, either
leaf or interior. However, due to an oversight, neither works on a "spare"
or "replacing" vdev. For example:

sudo zpool create foo raidz1 c1t5000CCA000081D61d0 c1t5000CCA000186235d0 spare c
1t5000CCA000094115d0
sudo zpool replace foo c1t5000CCA000186235d0 c1t5000CCA000094115d0
$ zpool status foo pool: foo

            spare-1                  ONLINE       0     0     0
              c1t5000CCA000186235d0  ONLINE       0     0     0

        spares
          c1t5000CCA000094115d0      INUSE     currently in use
$ sudo zinject -d spare-1 -A degrade foo
cannot find device 'spare-1' in pool 'foo'
$ sudo zpool clear foo spare-1
cannot clear errors for spare-1: no such device in pool

Even though there was nothing to clear, those commands shouldn't have
reported an error. by contrast, trying to clear "raidz1-0" works just fine:
$ sudo zpool clear foo raidz1-0
