Subject: [PATCH 48/54] 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.
