schemas: fix spurious warning about truncated snprintf output

Browse Source 
Fix warning:

    xmlschemas.c: In function 'xmlSchemaVAttributesComplex':
    xmlschemas.c:25506:63: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]
    xmlschemas.c:25506:29: note: 'snprintf' output between 3 and 13 bytes into a destination of size 12

On my system (GCC 13.2.1 x86_64) the warning only appears with -O0.
counter can't exceed 1000, so there's no real bug.
