[Mlir-commits] [mlir] [MLIR][NFC]Fix unusued variable warning. (PR #97813)

[Mats Petersson]

https://github.com/Leporacanthicus created https://github.com/llvm/llvm-project/pull/97813

This just changes a dyn_cast to and isa call to check for type, which avoids getting a warning in clang. The variable `ity` is not used in the next block.

No functional change.
