"of: overlay: add missing of_node_get() in __of_attach_node_sysfs"
added a missing of_node_get() to __of_attach_node_sysfs(). This
results in a refcount imbalance for nodes attached with
dlpar_attach_node(). The calling sequence from dlpar_attach_node()
to __of_attach_node_sysfs() is:
dlpar_attach_node()
of_attach_node()
__of_attach_node_sysfs()

***** UNTESTED. I need people with the affected PowerPC systems
***** (systems that dynamically allocate and deallocate
***** devicetree nodes) to test this patch.
