Change subject: mb/google/zork: Correct get board version and get fw config condition

Patch Set 5:

This based on if we know the return value 0 as success and otherwise failed. It's pretty common to use the below statement:
    if (rv != 0)
    	return rv;
But I checked the chromeec/ec.c. Looks like there are no consistent rule on this coding style. Some people check '!= 0' some didn't. What's you prefer?
