Subject: [PATCH] nvmem: Drop OF node reference on nvmem_add_one_cell() failure

If nvmem_add_one_cell() failed, the ownership of "child" (or "info.np"),
thus its OF reference, is not passed further and function should clean
up by putting the reference it got via earlier of_node_get().  Note that
this is independent of references obtained via for_each_child_of_node()
loop.
