CVE-2024-38384

If WRITE of ->lqueued is re-ordered with READ of 'bisc->lnode.next' in the loop of _blkcgrstatflush(), next_bisc can be assigned with one stat instance being added in blkcgroupbiostart(), then the local list in _blkcgrstat_flush() could be corrupted.

Fix the issue by adding one barrier.
