    sys/pci              if_dc.c 
  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.
