    Change iogrp property when retyping for Storwize/SVC

    If need migration when retyping, Storwize/SVC driver will add a copy
    of the volume first, and then start a task to check volume sync
    progress which will run each 10 mins. At last delete the origin copy
    when sync finished.

    But iogrp property is not a parameter of addvdiskcopy, so the iogrp
    of the copy volume is the same as the origin. If iogrp property is
    diff between the old and new volume type, the property will not
    change when retyped.
