serial: initialize retinfo in uart_get_info()

If this check ever triggers

static int uart_get_info(struct tty_port *port, struct serial_struct *retinfo)
{

uport = uart_port_check(state);
        if (!uport)
                goto out;

then all those sysfs users will print stack contents to userspace.
