[PATCH] knfsd: Check return value of lockd_up in write_ports
We should be checking the return value of lockd_up when adding a new socket to
nfsd. So move the lockd_up before the svc_addsock and check the return value.
The move is because lockd_down is easy, but there is no easy way to remove a
recently added socket.
