lib/ovs-atomic: Elaborate memory_order documentation.

The definition of memory_order_relaxed included a compiler barrier,
while it is not necessary, and indeed the following text on
atomic_thread_fence and atomic_signal_fence contradicted that.

memory_order_consume and memory_order_acq_rel are also more thoroughly
described.
