The code in vg_read():
```
if (missing_pv_dev || missing_pv_flag)
vg_mark_partial_lvs(vg, 1);
```
the missing_pv_dev not zero when pv->dev is null.
the missing_pv_flag not zero when pv->dev is not null but status MISSING_PV is
true.
any above condition will trigger code to set PARTIAL_LV.
So in _lv_mark_if_partial_single(), there should add '|| (!pv->dev)' case.
Below comment by David:
And the MISSING_PV flag was not used consistently, so there were cases
where pv->dev was null but the flag was not set. So to check for null dev
until it's more confidence in how that flag is used.
