tty: don't crash in tty_init_dev when missing tty_port
We currently warn the user when tty->port is not set in tty_init_dev
yet. The warning says that the kernel will crash later. And it really
will only few lines below at:
tty->port->itty = tty;
So be nice and avoid the crash -- return an error instead. And update
the warning.
