Fix 'zpool add' handling of nested interior VDEVs
When replacing a faulted device which was previously handled by a spare multiple levels of nested interior VDEVs will be present in the pool configuration; the following example illustrates one of the possible situations: NAME STATE READ WRITE CKSUM testpool DEGRADED 0 0 0 raidz1-0 DEGRADED 0 0 0 spare-0 DEGRADED 0 0 0 replacing-0 DEGRADED 0 0 0 /var/tmp/fault-dev UNAVAIL 0 0 0 cannot open /var/tmp/replace-dev ONLINE 0 0 0 /var/tmp/spare-dev1 ONLINE 0 0 0 /var/tmp/safe-dev ONLINE 0 0 0 spares /var/tmp/spare-dev1 INUSE currently in use This is safe and allowed, but get_replication() needs to handle this situation gracefully to let zpool add new devices to the pool.

+# DESCRIPTION:
+# 'zpool add' works with nested replacing/spare vdevs
+#
+# STRATEGY:
+# 1. Create a redundant pool with a spare device
+# 2. Manually fault a device, wait for the hot-spare and then replace it:
+# this creates a situation where replacing and spare vdevs are nested.
+# 3. Verify 'zpool add' is able to add new devices to the pool.
