mm, thp: allow fallback when pte_alloc_one() fails for huge pmd
The transparent hugepages feature is careful to not invoke the oom killer when a hugepage cannot be allocated. pte_alloc_one() failing in __do_huge_pmd_anonymous_page(), however, currently results in VM_FAULT_OOM which invokes the pagefault oom killer to kill a memory-hogging task. This is unnecessary since it's possible to drop the reference to the hugepage and fallback to allocating a small page.
