Since "drivers: base: Move cpu_dev_init() after node_dev_init()", we can remove some redundant code. node_dev_init() will walk through the nodes calling register_one_node() on each. This will trickle down to __register_one_node() which walks all present CPUs, calling register_cpu_under_node() on each. register_cpu_under_node() will call get_cpu_device(cpu) for each, which will return NULL until the CPU is registered using register_cpu(). This now happens _after_ node_dev_init(). Therefore, calling register_cpu_under_node() from __register_one_node() becomes a no-op, and can be removed.
