Don't use implicit QAtomic* casts in QFreeList

Pair the _next.testAndSetRelease() call in QFreeList<T>::release() with
_next.loadAcquire(), to ensure that the update to the bucket
being released is properly fenced.

QFreeList<T>:next() does not need a release fence, only an acquire fence,
which is placed on the memory bucket address load.
