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.
