    Remove dest node allocations during live migration rollback
    
    When a live migration fails or is cancelled, either during
    pre_live_migration on the destination host or during the
    actual live migration itself, we rollback from the failure/abort
    by doing things like removing volume connections from the
    destination host and re-setup the network on the source host.
    
    As part of the rollback from a failed or cancelled live migration,
    we also need to remove the allocations created in Placement for the
    destination node, since the instance is not on the destination
    node.
