From commit
a94e4f24ec83 ("MIPS: init: Drop boot_mem_map") onwards,
add_memory_region() is handled by memblock_add()/memblock_reserve()
directly and all bootmem API should be converted to memblock API.
Otherwise it will lead to boot failure, especially in the NUMA case
because add_memory_region lose the node_id information.

- Invert node_id check to de-indent the switch statement & avoid lines
over 80 characters.
- Fixup commit reference in commit message.]
