[Mlir-commits] [mlir] [mlir][tosa][linalg] Use `typeConverter->convertType<T>` (NFC) (PR #150578)

[Longsheng Mou]

https://github.com/CoTinker created https://github.com/llvm/llvm-project/pull/150578

Since `resultTy` might be nullptr, we should use `dyn_cast` instead of `cast`. Additionally, `typeConverter->convertType<T>` is more appropriate in this context.
