[PATCH] drivers/base/node: Fix cleanup path of node_init_node_access()

[Li Ming]

In node_init_node_access(), it frees the device when device_register()
fails. But per the description of device_register(), should use
put_device() to give up the device reference when device_register()
fails, rather than freeing the device directly.
