    VMware: Handle concurrent inventory folder create

    Cinder volumes are organized under vCenter inventory folder
    with name given by config option vmware_volume_folder. During
    volume creation, this folder is created only if it doesn't
    exist. Concurrent volume create operations when there is no
    such folder can result in a race condition-- some of the
    create operations will fail due to already existing folder.
    This patch fix this by ignoring the exception and returning a
    reference to the existing folder.
