How about creating a helper macro to go from ${device}State to 
DeviceState, then kill the wrapper function?  i.e something like this:

#define TO_QDEV_STATE(state) (&((state)->dev.qdev))

Then have one reset function which accepts DeviceState.  The call sites 
which have RTL8139State at hand can use rtl8139_reset(TO_QDEV_STATE(s));
