Before this patch, driver generated random MAC address every time it
was initialized. After that random MAC address could be overwritten
with fixed one, if provided.

I don't quite get where the advantage is supposed to be. Is it that
"use_eeprom" is set, but reading fails?

The only case where this helps is if wl1251_read_eeprom_mac() succeeds
but reads invalid address.
