Some fixes so that MSHR's are matched and we don't issue overlapping requests with detailed cpu

src/mem/cache/base_cache.cc:
    If we still have outstanding requests, need to schedule event again
src/mem/cache/miss/miss_queue.cc:
    Need to use block size so overlapping requests match in the MSHR's
src/mem/cache/miss/mshr.cc:
    Actually save the address, otherwise we can't match MSHR's
