Peter Hutterer 0f10cfd4b9 Xi: check for invalid modifiers for XI2 passive grabs
The other values are checked correctly, but if a modifier was outside the
allowed range, it would go unnoticed and cause a out-of-bounds read error for
any mask equal or larger than 256. The DetailRec where we store the grab masks
is only sized to 8 * sizeof(Mask).
