Fixes for uni-coherence in timing mode for FS.

Still a bug in atomic uni-coherence in FS.

src/cpu/o3/fetch_impl.hh:
src/cpu/o3/lsq_impl.hh:
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    Make CPU models handle coherence requests
src/mem/cache/base_cache.cc:
    Properly signal coherence CSHRs
src/mem/cache/coherence/uni_coherence.cc:
    Only deallocate once
