Without this patch a failure to rpcb_unset() is reported when the daemon is terminated for this case. This is harmless noise, but this patch avoids calling rpcb_unset() for the NFSv4 only case, avoiding the noise. When called with "-d", it still does the rpcb_unset(), assuming that the configuration might have been changed to NFSv4 only and unregistering with rpcbind() might still be needed.
