    libc/net: Fix some issues in our inet6_opt_init() (from RFC 3542).
    
    * The RFC says (in section 10.1) that only when extbuf is not NULL,
      extlen shall be checked, so don't perform this check when NULL is
      passed.
    
    * socklen_t is unsigned, so checking extlen for less than zero is
      not needed.
