    Storwize: remove SCSI LUN ID for volume attaching

    The VDisk-to-host mapping may fail due to the SCSI LUN
    id is already used by other VDisk mapping to this host,
    which is caused by serveral cinder volume nodes run
    parallelly and serveral volumes attaching parallelly.

    storwize volume driver does not need to calculate SCSI LUN
    ID locally for volume attaching. The SCSI LUN ID can be
    decided by storage backend correctly.
