net ads dns register doesn't take any arguments anymore.

	# net ads dns register hostname.domain 10.0.0.1
	net ads dns register <name> <ip>

These arguments have been removed in r21194 (or actually, they got sync'd into SAMBA_3_0_25 at that rev).

The offending code is net_ads.c:1722 in net_ads_dns_register()

        if (argc > 0) {
                d_fprintf(stderr, "net ads dns register <name> <ip>\n");
                return -1;
        }
