memory_hotplug: check for walk_memory_resource() failure in online_pages()
Add a check to online_pages() to test for failure of
walk_memory_resource(). This fixes a condition where a failure
of walk_memory_resource() can lead to online_pages() returning
success without the requested pages being onlined.
