    s_server: Add check for OPENSSL_strdup
    
    Since the OPENSSL_strdup() may return NULL if allocation
    fails, the 'port' could be NULL.
    And then it will be used in do_server(), which can accept
    NULL as an valid parameter.
    That means that the system could run with a wrong parameter.
    Therefore it should be better to check it, like the other
    memory allocation.
