069c7c30d1 Various fixes to delete packet and request a little better.
src/cpu/simple/timing.cc:
    Various updates for deleting requests more properly.

    The major change is moving the deletion of the fetch request/packet to after the instruction has executed and completed.  This should fix a few bugs because Ron's memory system didn't expect a call for a functional access while a timing access was being processed.

903a618714 Fix a bug to handle the fact that a CPU can send Functional accesses while a sendTiming has not returned in the call stack.
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.
