mm/sparse: introduce alloc_usemap_and_memmap
After commit 9bdac9142407 ("sparsemem: Put mem map for one node together."), vmemmap for one node will be allocated together, its logic is similar as memory allocation for pageblock flags. This patch introduces alloc_usemap_and_memmap to extract the same logic of memory alloction for pageblock flags and vmemmap.
