x86_64: fix setup_node_bootmem to support big mem excluding with memmap
typical case: four sockets system, every node has 4g ram, and we are using:
memmap=10g$4g
to mask out memory on node1 and node2
when numa is enabled, early_node_mem is used to get node_data and node_bootmap.
if it can not get memory from the same node with find_e820_area(), it will
use alloc_bootmem to get buff from previous nodes.
so check it and print out some info about it.
need to move early_res_to_bootmem into every setup_node_bootmem.
and it takes range that node has. otherwise alloc_bootmem could return addr
that reserved early.
depends on "mm: make reserve_bootmem can crossed the nodes".
