standalone uda bug +FIX

[Steven M. Schultz]

Subject: standalone uda bug +FIX
Index:	sys/pdpstand/ra.c 2.10BSD

Description:
  Some small errors in the stand alone RA driver for 2.10.1.  Mostly
checking for the result of a call to racmd < 0 which isn't going to work
since it returns a pointer type result and a missing argument in one call.

  Thanks for spotting this one Casey.

	Examination of the source.
