  Log:
  Fix the broken VT_WAITACTIVE ioctl for the case where the third arg
  was 0.
  
  PR:		4164
  Submitted by:	Joe Traister <traister@mojozone.org>
  
  While i was at it, also fixed a broken return value for the VT_RELDISP
  ioctl, iff the third arg was legally VT_TRUE, but the destination
  screen was in process mode so the actual switch had to be deferred.
  This was breaking the ability to directly toggle between two X servers
  running on two VTs, since the server getting the bogus error return
  was running wild, and competing with the other one for the hardware.
  (Sigh, this was a very long-standing bug.)
