mm/memory_hotplug: remove nid parameter from remove_memory() and friends

There is only a single user remaining.  We can simply lookup the nid only
used for node offlining purposes when walking our memory blocks.  We don't
expect to remove multi-nid ranges; and if we'd ever do, we most probably
don't care about removing multi-nid ranges that actually result in empty
nodes.

If ever required, we can detect the "multi-nid" scenario and simply try
offlining all online nodes.
