CoreplexNetwork: don't force a buffer on the coherence manager

Let the l2Config.coherenceManager create its own appropriate buffers.
This can matter if you need to make sure the buffer is in the right
place in the hierarchy for hierarchical place and route.

Fix FPU control bug for div/sqrt
...
I was examining a WB-stage control signal instead of a MEM-stage control
signal. I refactored the code to group the signals together, so that this
sort of bug is less likely going forward.
