x86: Call early_res_to_bootmem one time

Browse source 
Simplify setup_node_mem: don't use bootmem from other node, instead
just find_e820_area in early_node_mem.

This keeps the boundary between early_res and boot mem more clear, and
lets us only call early_res_to_bootmem() one time instead of for all
nodes.
