r8169: restore mac addr in rtl8169_remove_one and rtl_shutdown
The newer chipsets (all PCI-E) are known that they need full power cycle
(AC or battery removal) to reset MAC address to a hardwired one. Previous
patch to address this problem loads the original MAC address from EEPROM.
But it brought other problem for which it is necessary to introduce a new
module parameter.
However, it might suffice to restore the initial MAC address before
shutdown/reboot/kexec and when removing the module.
