Modified files:
sys/pci if_dc.c
Log:
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.
