net: rtl8139: Pass private data into rtl8139_eeprom_delay()

Browse Source 
Instead of always calling rtl8139_eeprom_delay() with priv->ioaddr,
call it with priv and let the function access priv->ioaddr. This
reduces code duplication and has no impact, since the compiler will
inline this as needed anyway.
