  Fix llvm-mlir-use-after-erase findings (#210733)

Fix the following warnings identified by the `llvm-mlir-use-after-erase`
check from https://github.com/llvm/llvm-project/pull/210727:

```cpp
mlir/lib/Transforms/Utils/DialectConversion.cpp:2700:33: warning: operation 'op' is used after it was erased [llvm-mlir-use-after-erase]
 2700 |           curState, std::string(op->getName().getStringRef()) + " folder");
      |                                 ^
mlir/lib/Transforms/Utils/DialectConversion.cpp:2685:12: note: operation erased here
 2685 |   rewriter.replaceOp(op, replacementValues);
      |            ^
mlir/lib/Dialect/MemRef/Transforms/NormalizeMemRefs.cpp:440:29: warning: operation 'newOp' is used after it was erased [llvm-mlir-use-after-erase]
  440 |           Value newMemRef = newOp->getResult(resIndex);
      |                             ^
mlir/lib/Dialect/MemRef/Transforms/NormalizeMemRefs.cpp:459:20: note: operation erased here 
  459 |             newOp->erase();
      |                    ^
mlir/lib/Dialect/MemRef/Transforms/NormalizeMemRefs.cpp:440:29: note: the use happens in a later loop iteration than the erase
  440 |           Value newMemRef = newOp->getResult(resIndex);
      |                             ^
```

The warning at `NormalizeMemRefs.cpp:440` is resolved by breaking the
loop iteration after erasing the operation, similar to what is done at
line 306.
