PCMG: Disconnect coarsening from DMKSP propagation
- If a user called KSPSetComputeOperator() on the level solves before PCMG creates the level DMs,

for each subsequent coarsening, it will keep the top-level DMKSP and wipe out those on the coarser
levels.
- To fix this, I just decouple coarsening from KSPSetDM()
