Donet Tom a4ca1815e3 drivers/base/node: handle error properly in register_one_node() ...

[ Upstream commit 786eb990cf ]

If register_node() returns an error, it is not handled correctly.
The function will proceed further and try to register CPUs under the
node, which is not correct.

So, in this patch, if register_node() returns an error, we return
immediately from the function.
