  MFC 1.167: panic on attach failure...
  % When bus_alloc_resource_any() fails, dc_detach() is called and it
  % attempts to deallocate busdma tags and resources that haven't been
  % allocated yet, causing a panic every time a dc interface fails to
  % attach.  Fix by checking that we really have something to dealloc
  % before calling bus_dma*() functions.
