  -----------
  [mlir][cf] Do not access erased operation in `cf.cond_br` lowering (#148358)

Do not access the erased `cf.cond_br` operation in the lowering pattern.
That won't work anymore in a One-Shot Dialect Conversion and triggers a
use-after-free sanitizer error.

After the One-Shot Dialect Conversion refactoring, a
`ConversionPatternRewriter` will behave more like a normal
`PatternRewriter`.
