lockd: double unregister of inetaddr notifiers

Browse source

commit dc3033e16c upstream.

lockd_up() can call lockd_unregister_notifiers twice:
inside lockd_start_svc() when it calls lockd_svc_exit_thread()
and then in error path of lockd_up()

Patch forces lockd_start_svc() to unregister notifiers in all error cases
and removes extra unregister in error path of lockd_up().

Fixes: cb7d224f82 "lockd: unregister notifier blocks if the service ..."
