vgremove: select: direct selection to be done per-VG, not per-LV
Though vgremove operates per VG by definition, internally, it actually means iterating over each LV it contains to do the remove.
So we need to direct selection a bit in this case so that the selection is done per-VG, not per-LV.
That means, use processing handle with void_handle.internal_report_for_select=0 for the process_each_lv_in_vg that is called later in vgremove_single fn. We need to disable internal selection for process_each_lv_in_vg here as selection is already done by process_each_vg which calls vgremove_single. Otherwise selection would be done per-LV and not per-VG as we intend!
