lockd: fix NLMv4 GRANTED_MSG handling
GRANTED_MSG is a server-to-client callback, so it runs on the client,
where nfsd never registers nlmsvc_ops. The nlm4svc_lookup_host()
helper is for the server-side request handlers
(TEST/LOCK/CANCEL/UNLOCK), which reach nlmsvc_ops->fopen and must
reject requests when nfsd isn't running. GRANTED_MSG only calls
nlmclnt_grant(). Instead, of calling nlm4svc_lookup_host(), which
results in a client failing a GRANTED_MSG call, call
nlmsvc_lookup_host().
Fixes: 62721885e861 ("lockd: Use xdrgen XDR functions for the NLMv4 GRANTED_MSG procedure")
