src/mem/cache/base_cache.cc:
Sometimes a functional access comes while waiting on a outstanding packet being sent.
This could be because Timing CPU does some post processing on the recvTiming which send functional access.
Either the CPU should leave the pkt/req around (so They can be referenced in the mem system). Or the mem
system should remove them from outstanding lists and reinsert them if they fail in the sendTiming.
I did the later, eventually we should consider doing the former if that is the correct behavior.
