8250_men_mcb: Fix unsigned expression compared with zero
There is a warning reported by coccinelle:
./drivers/tty/serial/8250/8250_men_mcb.c:226:6-19: WARNING:
Unsigned expression compared with zero: data -> line [ i ] < 0
The array "line" of serial_8250_men_mcb_data is used to record the
registered serial port. When register a port failed, it will return
an error code, but the type of "line" is "unsigned int", causing
the error code to reverse. Modify the type of "data -> line" to solve
this problem.
Fixes: 2554e6ba28a2 ("8250_men_mcb: Read num ports from register data.")
