lockd: eliminate duplicate nlmsvc_lookup_host call from nlmsvc_lock
nlmsvc_lock calls nlmsvc_lookup_host to find a nlm_host struct. The callers of this function, however, call nlmsvc_retrieve_args or nlm4svc_retrieve_args, which also return a nlm_host struct. Change nlmsvc_lock to take a host arg instead of calling nlmsvc_lookup_host itself and change the callers to pass a pointer to the nlm_host they've already found. Since nlmsvc_testlock() now just uses the caller's reference, we no longer need to get or release it. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.
