Supply the match mask to prerequisities checking when available. This allows checking for zero-valued matches. Non-zero valued matches imply the presense of corresponding mask bits, but for zero valued matches we must explicitly check the mask, too. This is required now only for conntrack validity checking due to the conntrack state having and 'invalid' bit, but not 'valid' bit. One way to match an valid conntrack state is to match on the 'tracked' bit being one and 'invalid' bit being zero. The latter requires the corresponding mask bit be verified.
