coreutils/stty.c set_window_size() returns 0 on error

[Bakonyi Ferenc]

Hi all,

stty from GNU coreutils returns 1 on error:

localhost:~$ stty -F /dev/tty1 rows 999
stty: /dev/tty1: Invalid argument
localhost:~$ echo $?
1

While busybox stty returns 0:

localhost:~$ busybox stty -F /dev/tty1 rows 999
stty: /dev/tty1: Invalid argument
localhost:~$ echo $?
0

Suggested patch:
