Merge r259393 from head:
Fix several panics when initialization of an ISA or PC-CARD device fails: o Assign sc->an_dev in an_probe() (which isn't really a probe function in the standard newbus sense) as we may need it for printing errors. o Use device_printf() rather than if_printf() in an_reset() - this is called from an_probe() long before the ifp structure is initialised in an_attach(). o Initialize the ifp structure early in an_attach() as we use if_printf() in cases where allocation of descriptors etc fails.
