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.
