QFreeList: fix UB (data race) in release()
The load from _v[block] must acquire, to match the storeRelease()
implied in the testAndSetRelease() in next(), where _v[block] was
allocated. A loadReleaxed() will not establish the happens-before
relation required to avoid a data race.
So use loadAcquire().
Pick-to: 6.10 6.9 6.8 6.5
