Convert x86 to HAVE_MEMBLOCK_NODE_MAP. The only difference in memory
handling is that allocations can't no longer cross node boundaries
whether they're node affine or not, which shouldn't matter at all.
This conversion will enable further simplification of boot memory
handling.
-v2: Fix build failure on !NUMA configurations discovered by hpa.
