We might want to revisit the whole logic later, as there's in fact little reason why block read errors would be fatal when all other read errors are not. But I'd rather remove SMBus block support from the tool before attempting to clean up the code. Fixes: 7abc52d7792e ("Return the correct error code on I2C block read failure.")
