[PATCH] knfsd: call lockd_down when closing a socket via a write to nfsd/portlist
The refcount that nfsd holds on lockd is based on the number of open sockets.
So when we close a socket, we should decrement the ref (with lockd_down).
Currently when a socket is closed via writing to the portlist file, that
doesn't happen.
So: make sure we get an error return if the socket that was requested does is
not found, and call lockd_down if it was.
