s390/qdio: increase string buffer size
Avoid false positive warnings like this with gcc 7.1:
drivers/s390/cio/qdio_debug.h:63:4:
note: 'snprintf' output between 8 and 17 bytes into a destination of size 16
snprintf(debug_buffer, QDIO_DBF_LEN, text);
and simply increase the size of the string buffer.
