dmmgsetuplevel() no longer calls KSPSetOperators for the MG levels
it is now properly called as needed in DMMGSolveKSP

Hg-commit: 63e337e9ec16f0e4f46b65aa3437caefa145bb07

1) change to dmmg so KSPSetOperators is not called earlier
with empty matrix (not a bug fix, just cleanup)
2) SNESSetJacobian() no longer calls KSPSetOperators()
that is called directly in SNES

1) change to dmmg so KSPSetOperators is not called earlier

3) PCSetUp_MG() now calls KSPSetOperators on finest grid
smoother if user has not reset it.
4) DAMG will not call KSPSetOperators() on finest grid
smoother, now MG automatically updates it if the PCMG
Operator is reset
