[PATCH] knfsd: add a callback for when last rpc thread finishes

Browse Source 
nfsd has some cleanup that it wants to do when the last thread exits, and
there will shortly be some more.  So collect this all into one place and
define a callback for an rpc service to call when the service is about to be
destroyed.
