RPC scan broken

It seems that the RPC scan (-sR) is totally broken in Nmap
versions 2.54BETA29 .. BETA32.

In nmap.c, the RPC scanning is started as:

  if (o.rpcscan)  pos_scan(currenths, NULL, 0, RPC_SCAN);

But in the pos_scan() function in scan_engine.c, there's a test:

  void pos_scan(struct hoststruct *target, u16 *portarray, int numports, 
                stype scantype) {
  if (! numports) return;                /* nothing to scan for */

And because "numports" is always 0, the scan is never run.
Fix: "if (!numports && (scantype != RPC_SCAN)) return;"

Best regards,
