[PATCH] knfsd: nfsd4: add missing rpciod_down()
We should be shutting down rpciod for the callback channel when we shut down
the server.
Also note that we do rpciod_up() and create the callback client *before*
setting cb_set--the cb_set only determines whether the initial null was
succesful. So cb_set is not a reliable determiner of whether we need to clean
up, only cb_client is.
