    s390 FC device path fix for Ubuntu

    This fix solves a LUN attachment error for Ubuntu on s390 host setups. Fiber
    Channel requires a path for discovery of new devices, and Ubuntu uses a
    different format than previously assumed. This can be solved by simply adding
    the Ubuntu-style path to the list of possible paths, since they get quietly
    dropped if they lead nowhere in FibreChannelConnector._get_possible_volume_paths
    anyways.
