[    0.000000] SRAT: SRAT not used.

the early_node_map is not sorted because node0 with non zero start come first.

so try to sort it right away after all regions are registered.

also fixs refression by 8716273c (x86: Export srat physical topology)

-v2: make it more solid to handle cross node case like node0 [0,4g), [8,12g) and node1 [4g, 8g), [12g, 16g)
-v3: update comments.

23b6c52cf5 x86: Decrease the level of some NUMA messages to KERN_DEBUG
Some NUMA messages in srat_32.c are confusing to users,
because they seem to indicate errors, while in fact they
reflect normal behaviour.

Decrease the level of these messages to KERN_DEBUG so that
they don't show up unnecessarily.
