Batch the page count updates instead of doing them one at a time. By doing
this we can improve the overall performance as the atomic increment
operations can be expensive due to the fact that on x86 they are locked
operations which can cause stalls. By doing bulk updates we can
consolidate the stall which should help to improve the overall receive
performance.
