Xen can reserve huge amounts of memory for pre-ballooning, but that still shows as RAM in the e820 memory map. early_node_mem could not find range because of start/end adjusting, and will go through the fallback path. However, the fallback patch is still using memblock_x86_find_range_node(), and it is partially top-down because it go through active_range entries from low to high. Let's use memblock_find_in_range instead memblock_x86_find_range_node. So get real top down in fallback path. We may still need to make memblock_x86_find_range_node to do overall top_down work.
