S2IO: Restoring the mac address in s2io_reset
- Restore in s2io_reset, the mac address assigned during s2io_open. Earlier, it was getting overwritten to the factory default (read from the eeprom) and subsequently dropping received frames. - Fixed the typo in calling rtnl_unlock in s2io_set_link function.
