  SVN rev 191443 on 2009-04-23 21:41:37Z by rwatson
  
  Reorganize in_control() so that invariants are more obvious, and so
  that it is easier to lock:
  
  - Handle the unsupported ioctl case at the beginning of in_control(),
    handing off to ifp->if_ioctl, rather than looking up interfaces and
    addresses unnecessarily in this case.
  
  - Make it an invariant that ifp is always non-NULL when running
    in_control()-implemented ioctls, simplifying the code structure.
