Documentation/memory-barriers.txt: Add needed ACCESS_ONCE() calls to memory-barriers.txt
The Documentation/memory-barriers.txt file was written before
the need for ACCESS_ONCE() was fully appreciated. It therefore
contains no ACCESS_ONCE() calls, which can be a problem when
people lift examples from it. This commit therefore adds
ACCESS_ONCE() calls.
