[PATCH] Another couple of alterations to the memory barrier doc

Make another couple of alterations to the memory barrier document following
suggestions by Alan Stern and in co-operation with Paul McKenney:

 (*) Rework the point of introduction of memory barriers and the description
     of what they are to reiterate why they're needed.

 (*) Modify a statement about the use of data dependency barriers to note that
     other barriers can be used instead (as they imply DD-barriers).
