hugetlb: move all the in use pages to active list 



When we fail to allocate pages from the reserve pool, hugetlb tries to
allocate huge pages using alloc_buddy_huge_page.  Add these to the active
list.  We also need to add the huge page we allocate when we soft offline
the oldpage to active list.
