    Catch new iscsi exception

    A while back we fixed up a target create/update error
    that was identified in the gating tests:
        https://review.openstack.org/#/c/47513/

    Since then a new patch was introduced to to the update and separate
    it so that it could easily be used in other places.
        https://review.openstack.org/#/c/58599/

    The problem is this added a new exception "TargetUpdate" and
    didn't add this to the except block that we have.

    This patch changes the catch block to handle the new exception and
    do the retry, thereby putting the original fix back in place.
