After reading through the Gerrit code I'm beginning to think that not
setting a function has it default to MaxWithBlock and this doesn't get
rejected like an explicit setting of MaxWith Block. This means we may
not be properly exercising our new submit requirement rule for Verified.
Switch it to NoBlock explicitly to exercise the submit requirements.
