mm/hugetlb.c: fix warning on freeing hwpoisoned hugepage
Fix the warning from __list_del_entry() which is triggered when a process tries to do free_huge_page() for a hwpoisoned hugepage. free_huge_page() can be called for hwpoisoned hugepage from unpoison_memory(). This function gets refcount once and clears PageHWPoison, and then puts refcount twice to return the hugepage back to free pool. The second put_page() finally reaches free_huge_page().
