fbdev: sisfb: Fix strbuf array overflow

In the Linux kernel, the following vulnerability has been resolved:

fbdev: sisfb: Fix strbuf array overflow

The values of the variables xres and yres are placed in strbuf.
These variables are obtained from strbuf1.
The strbuf1 array contains digit characters
and a space if the array contains non-digit characters.
Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres);
more than 16 bytes will be written to strbuf.
It is suggested to increase the size of the strbuf array to 24.
