  [mlir][SPIRV] Do not access erased op in SPIRV->LLVM lowering (#148373)

This commit fixes two occurrences where an erased op was accessed at a
later point of time. 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`.
