mem: Fix bug relating to writebacks and prefetches

Previously the code commented about an unhandled case where it might be
possible for a writeback to arrive after a prefetch was generated but
before it was sent to the memory system.  I hit that case.  Luckily
the prefetchSquash() logic already in the code handles dropping prefetch
request in certian circumstances.
