zpool iostat allows you to specify only certain vdevs to display.
Currently, if you run 'zpool iostat -c CMD vdev1 vdev2 ...'
on specific vdevs, it will actually run the command on *all* vdevs,
and just display the results for the vdevs you specify. This patch
corrects the behavior to only run the command on the specified vdevs,
and also enables the zpool_iostat_005_pos.ksh tests.
