Prefetch: Don't prefetch if address is in the write queue. Check that we're not currently writing back an address the prefetcher is trying to prefetch before issuing it. We previously checked the mshrQueue and the cache itself, but forgot to check the writeBuffer. This fixes a memory corrucption issue with an L2 prefetcher.
