[Tablegen][PredicateExpander] Fix a bug in `expandCheckImmOperand`.
Function `expandCheckImmOperand` should always check if the input machine
instruction is passed by reference before calling method `getOperand()` on it.
Found while working on a patch that relies on `expandCheckImmOperand` to expand
a scheduling predicate.
