hugetlb: fix dynamic pool resize failure case
When gather_surplus_pages() fails to allocate enough huge pages to satisfy the requested reservation, it frees what it did allocate back to the buddy allocator. put_page() should be called instead of update_and_free_page() to ensure that pool counters are updated as appropriate and the page's refcount is decremented.
