of_attach_node() and of_detach_node() always return zero, so
their return value is meaningless.

But should they always return zero?

At least __of_attach_node_sysfs() can fail in several ways.

And there's also this in __of_detach_node() which should probably be
returning an error:

	if (WARN_ON(of_node_check_flag(np, OF_DETACHED)))
        	return;


Seems to me we should instead be fixing these to propagate errors,
rather than hiding them?
