[CIR][NFC] Fix mismatch of argument type in IR tests (#837)

There is a typo in `call.cir` that uses a wrong function argument type,
leading to failure in the final LLVM IR translation.

CIR verification does not reject it, because it skips indirect calls at
the beginning. It's `verifySymbolUses` after all.

The typo was copied to another IR test. Here we fix them all.
