[PATCH] serverworks: Switch to pci refcounted interfaces

[PATCH] serverworks: Switch to pci refcounted interfaces

[Alan Cox]

As we don't support hotplug we end up leaking an isa_dev reference which
if unload was ever added we would drop at the end of unloading. This is
fine because we do genuinely need the isa_dev pointer until unload.
