Subject: mm/memory: return -ENOMEM for page-table allocation failure in insert_pages()

walk_to_pmd() returns NULL only when p4d_alloc(), pud_alloc(), or pmd_alloc() fails. These are page-table allocation failures, but insert_pages() currently reports them as -EFAULT.

Return -ENOMEM instead, consistent with the subsequent pte_alloc() failure and with the single-page insert_page() path, which reports failure of the same page-table allocation chain as -ENOMEM.

Address and range validation failures in vm_insert_pages() continue to return -EFAULT. Keep the later -EFAULT return for pte_offset_map_lock(), which is not an allocation failure.
