    fix error on delete interface when destroying instance

    An instance may be destroyed prior nova-compute receives a
    vif-delete-event. detach_interface() will so try to get the lxd
    profile related to the instance which does not exist anymore, the
    process will fail with a NotFound exception raised by lxclib.

    In this commit we solve the issue by handling the exception and so
    avoiding on updatating the lxc profile. We still continue the process
    of vif_driver.un_plug() to ensure all got cleaned.
