    [IBM DS8000] Fixed Detach for multi-attach volumes

    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 multiple hosts, then skip
    the delete host operation and return.
