Subject:   [CFR][ZFS] Show "previous device location" for removed vdevs

[-- Attachment #1 --]
When a vdev cannot be found during ZFS pool import/mount time, "zpool 
status"
reports the device GUID and a "device was at" message as a user aid.  This
patch provides the same behavior when a device is removed post zpool
mount/import.
