    Address masking issue during auto-allocation failure

    If an interface could not successfully be plugged to a router
    during the provisioning of external connectivity, a failure
    is triggered, and a subsequent cleanup performed.

    This patch ensures that the cleanup accounts only for the
    subnets that were uplinked successfully, thus fixing the
    incomplete cleanup, and the masking user error that resulted
    otherwise.
