Revert "r8169: mac address change support"

This reverts commit a2b98a6.

As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.

Says Francois:

  "Go revert it.

   Despite what I claimed, I can not find a third-party confirmation by
   email that it works elsewhere.

   It would probably be enough to remove the call to
   __rtl8169_set_mac_addr() in rtl8169_hw_start() though."
