Fix initialization of fake LSN for unlogged relations

9155580 has changed the value of the first fake LSN for unloggedrelations from 1 to FirstNormalUnloggedLSN (aka 1000), GiST requiring anon-zero LSN on some pages to allow an interlocking logic to work, butits value was still initialized to 1 at the beginning of recovery orafter running pg_resetwal. This fixes the initialization for both codepaths.Author: Takayuki TsunakawaReviewed-by: Dilip Kumar, Kyotaro Horiguchi, Michael PaquierDiscussion:https://postgr.es/m/OSBPR01MB2503CE851940C17DE44AE3D9FE6F0@OSBPR01MB2503.jpnprd01.prod.outlook.comBackpatch-through: 12
