PATCH 2/2 cio: Register/unregister subchannels only from kslowcrw.

In reply to Martin Schwidefsky

From: Cornelia Huck <[email protected]>

Make sure all subchannel handling is done on the slow path workqueue so that we don't have races between an old subchannel unregistering and a new subchannel with the same name registering.
