    cmdgen: add missing null pointer check in --dump mode.
    
    A user pointed out that once we've identified the key algorithm from
    an apparent public-key blob, we call ssh_key_new_pub on the blob data
    and assume it will succeed. But there are plenty of ways it could
    still fail, and ssh_key_new_pub could return NULL.
