Use fixPacket function everywhere.
Fix fixPacket assert function.
Stop timing port from forwarding the request if a response was found in its queue on a read.

Add parameter to configure what percentage of mem accesses are functional
src/mem/cache/base_cache.cc:
src/mem/cache/cache_impl.hh:
Use fix Packet function
src/mem/packet.cc:
