[PATCH] of: overlay: Fix missing of_node_put() in error case of init_overlay_changeset()

[Kunihiko Hayashi]

In init_overlay_changeset(), the variable "node" is from
of_get_child_by_name(), and the "node" should be discarded in error case.

Fixes: d1651b03c2df ("of: overlay: add overlay symbols to live device tree")
