lockd: simplify management of network status notifiers
Now that the network status notifiers use nlmsvc_serv rather then nlmsvc_rqst the management can be simplified. Notifier unregistration synchronises with any pending notifications so providing we unregister before nlm_serv is freed no further interlock is required. So we move the unregister call to just before the thread is killed (which destroys the service) and just before the service is destroyed in the failure-path of lockd_up(). Then nlm_ntf_refcnt and nlm_ntf_wq can be removed. Signed-off-by:NeilBrown <neilb@suse.de> Signed-off-by:
