Donet Tom 53683b4d37 drivers/base/node: fix double free in register_one_node() 
[ Upstream commit 0efdedfa537eb534c251a5b4794caaf72cc55869 ]

When device_register() fails in register_node(), it calls
put_device(&node->dev).  This triggers node_device_release(), which calls
kfree(to_node(dev)), thereby freeing the entire node structure.

As a result, when register_node() returns an error, the node memory has
already been freed.  Calling kfree(node) again in register_one_node()
leads to a double free.

This patch removes the redundant kfree(node) from register_one_node() to
prevent the double free.
