    VMware: Fix volume cascade delete

    VMDK driver does not allow snapshot deletion if the volume
    is attached. Currently we assume the volume to be attached
    if it's state is not 'available', which is wrong. During
    cascade delete, the volume status is set to 'deleting'.
    Therefore, snapshot deletion fails even if the volume is
    not attached. Fixing this by using volume attachment info
    to check for attached volumes.
