fru-device: Refine addressing mode detection logic

Existing EEPROM addressing mode detection logic doesn't work on some
devices (24C128 in my case) after an AC cycle so refine the logic
by setting the higher data word address bits to 0. It's safe on 8-bit
addressing EEPROMs because it doesn't write any actual data.

Tested: Both 8-bit and 16-bit EEPROMs were detected as expected.
