eepro100: Remove unused device status entries

Once upon the time when QEMU hacking was fun
there was a brave knight who wanted to have
a driver for a special intel nic.

So he started by cloning ne2000.c which also
meant that the new born eepro100.c was
immediately three years old.

Other knights who also wanted to have fun and
take their part in the battle thought that it
would be a good idea to remove stupid code
which says "missing nic load, missing nic save".

They saved everything they saw, man and women,
ne2000 code and runtime address offsets, and
put all saved elements in a prison called
vm data.

When the first knight came back and noticed
the unhappy prisoners, he wanted to set them
free. But the keepers of the keys told him
that they would have to stay there forever
for compatibility reasons.

So our brave knight now takes a new effort
to save the souls of the poor prisoners by
removing their names.

Their bodies will have to rot in the dungeons
of compatibility forever, watched by the
keepers of the keys.
