Bug #14676111 WRONG PAGE_LEVEL WRITTEN FOR UPPER THAN FATHER PAGE AT BTR_LIFT_PAGE_UP()
btr_lift_page_up() writes wrong page number (different by -1) for upper than father page.
But in almost all of the cases, the father page should be root page, no upper
pages. It is very rare path.
In addition the leaf page should not be lifted unless the father page is root.
Because the branch pages should not become the leaf pages.
