    Fixes race condition in LVMVolumeDriver create_cloned_volume method

    When we create a clone volume, LVMVolumeDriver will firstly create a temp
    snapshot for copying, the temp snapshot name is
    "clone-snap-%s" % source_volume['id']. When we create multiple clone volumes
    of the same volume simultaneously, which would trigger the race issuse.

    I changes the temp snapshot name template to "clone-snap-%s" % volume['id'],
    so temp snapshot name will be unique.

    Fixes bug #1202139
