  SVN rev 222922 on 2011-06-10 09:51:15Z by mav
  
  MFC r206112, r208928 (by mjacob):
  Rearrange how things are done to avoid dereferencing stale pointers in
  the case of immediate unconfigure after configure. Hold the periph an
  extra count while we have the task to create sysctl context outstanding
  so that the periph doesn't go away unexpectedly.
