8250_men_mcb: Fix unsigned comparison with less than zero

Browse source

The data->line[i] is defined as unsigned int type, if(data->line[i] < 0)
is invalid, so replace data->line[i] with res.

./drivers/tty/serial/8250/8250_men_mcb.c:223:6-19: WARNING: Unsigned expression compared with zero: data->line[i] < 0.
