ed_probe_rtl80x9. In the pci case we call ed_probe_rtl80x9 first. In the PCI case we were using the correct nic_offset by accident because softc is initialized to zero. In the isa case we were using the wrong value by accident, since ed_probe_WD80x3 sets the offset value to 0x10. This lead to the identification routines failing. Fix this problem by always initalizing the nic_offset and asic_offset before making ed_{asic,nic}_{in,out}* calls.
