Until now, every dat table allocated to map a guest was put in a linked list. The page->lru field of struct page was used to keep track of which pages were being used, and when the gmap is torn down, the list was walked and all pages freed. This patch gets rid of the usage of page->lru. Page tables are now freed by recursively walking the dat table tree. Since s390_unlist_old_asce() becomes useless now, remove it.
