HEAD broken if -u ntp:ntp

[Hal Murray]

It crashes with 
Apr 14 04:00:30 fed ntpd[4726]: invalid op: 110

110 decimal is ascii u

This looks suspicious, but I'm sacking out.

    ntpd; add missing default case, fix a bad exit() code.

...

            case 'Z':
                if (ntp_optarg != NULL)
                        set_sys_var(ntp_optarg, strlen(ntp_optarg) + 1, 
(u_short) (RW | DEF));
-               break;
+                break;
+            default:
+               msyslog(LOG_ERR, "invalid op: %d", op);
+               exit(1);
            }
        }

There are two loops scanning the command line args.
