[PATCH 6/7] of: add consistency check to of_node_release()

[Frank Rowand]

Add an additional consistency check to of_node_release(), which is
called when the reference count of a devicetree node is decremented
to zero.  The node's children should have been deleted before the
node is deleted so check that no children exist.
