Avoid invoking open(2) with console->tty_dev as NULL:

```
[12/34] Compiling C object obmc-console-server.p/console-server.c.o
../../../console-server.c:263:20: warning: Null pointer passed to 1st parameter expecting 'nonnull' [core.NonNullParamChecker]
        console->tty_fd = open(console->tty_dev, O_RDWR);
                          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
