of: Fix a refcounting bug in __of_attach_node_sysfs()
The problem in this code is that if kobject_add() fails, then it should
call of_node_put(np) to drop the reference count. I've actually moved
the of_node_get(np) later in the function to avoid needing to do clean
up.
Fixes: 5b2c2f5a0ea3 ("of: overlay: add missing of_node_get() in __of_attach_node_sysfs")
