Verbatim imports can cause hostid mismatches, but things otherwise work. `zpool
status` does not handle this and will fail when assertions are enabled:
```
zpool: ../../cmd/zpool/zpool_main.c:4418: status_callback: Assertion `reason == ZPOOL_STATUS_OK' failed.
Program received signal SIGABRT, Aborted.
```
Lets instead add a case to display an informative message such as this:
```
pool: rpool
state: ONLINE
status: Mismatch between pool hostid and system hostid on imported pool.
This pool was previously imported into a system with a different hostid,
and then was verbatim imported into this system.
action: Export this pool on all systems on which it is imported.
Then import it to correct the mismatch.
