Fix bug that prevented listing of multipath disks when replacing a disk

Sorry new case is https://ixsystems.atlassian.net/browse/NAS-105059#icft=NAS-105059

Opened new case. https://ixsystems.atlassian.net/browse/NAS-101599#icft=NAS-101599    This appears to be the exact same issue however. I have a prod server right now that I cannot replace the drive on because it failed to allow me to select "multipath/disk2" as the replacement.

@Joe Maloney - Is there any way to upload debugs without them being open to the public. In many cases there is way to much specific information in there that should be open to the world.

@Robert Blayzor We cannot reproduce this internally even with the original reporter included.  Please create a new ticket with a debug by going to System -> Advanced, click Save Debug, and upload the attachment to the new ticket.

Reopening ticket for investigation if this exact issue still exists or if we need to open a related ticket for a similar issue.
