    [SVf] Fixed Detach for multi-attach volumes

    [Spectrum Virtualize family] During detach operation
    for Multi attach type volumes the first detach
    from the host is successful. In the second detach
    operation the volume remains in detaching state.

    Fixed the above issue by adding a check for multi-attach
    volumes and get the host mapping info of a volume.
    if the volume is attached to single host skip the
    terminate connection function and return.

    closes bug: #1941694
