drm/xe/oa: Limit num_syncs to prevent oversized allocations
In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Limit num_syncs to prevent oversized allocations The OA open parameters did not validate num_syncs, allowing userspace to pass arbitrarily large values, potentially leading to excessive allocations. Add check to ensure that num_syncs does not exceed DRM_XE_MAX_SYNCS, returning -EINVAL when the limit is violated. v2: use XE_IOCTL_DBG() and drop duplicated check. (Ashutosh) (cherry picked from commit e057b2d2b8d815df3858a87dffafa2af37e5945b)
