Commit 40dae7ec537, which made the handling of interrupted nbtree page splits more robust, removed an nbtree-specific end-of-recovery cleanup step. This meant that it was no longer possible to complete an interrupted page split during recovery. However, a reference to recovery as a reason for using a NULL stack while inserting into a parent page was missed. Remove the reference. Remove a similar obsolete reference to recovery that was introduced much more recently, as part of the btree fastpath optimization enhancement that made it into Postgres 11 (commit 2b272734, and follow-up commits). Backpatch: 11-, where the fastpath optimization was introduced.
