x86, memblock: Fix early_node_mem with big reserved region.
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.
