virtio-scsi currently has limit of 8 outstanding notifications so when more that
8 LUNs are unplugged, some are missed.
Commit 5ff843721467 ("scsi: virtio_scsi: unplug LUNs when events missed")
Fixed this by checking the 'event overflow' bit and manually scanned the bus
to see which LUNs are still there.
However there is a corner case when all LUNs are unplugged.
In this case (which is not fully scsi confirmant IMHO), all scsi
commands to such device respond with INVALID TARGET.
This patch proposes to detect this and remove the LUN in this case
as well.
