toollib: fix segfault when handling selection with historical LVs
When processing historical LVs inside process_each_lv_in_vg for selection, we need to use dummy "_historical_lv" for select_match_lv. This is because a historical LV is not an actual LV, but only a tiny representation with subset of original properties that we recorded (name, uuid...). To use the same processing functions we use for full-fledged non-historical LVs, we need to use the prefilled "_historical_lv" structure which has all the other missing properties hard-coded.
