Allocation of numa_distance uses memblock_phys_alloc_range() to limit
allocation to be below the last mapped page.

But NUMA initializaition runs after the direct map is populated and
there is also code in setup_arch() that adjusts memblock limit to
reflect how much memory is already mapped in the direct map.

Simplify the allocation of numa_distance and use plain memblock_alloc().
