LOG: [ObjC Availability] Add missing const to getVersion function of ObjCAvailabilityCheckExpr class

Add missing const to `getVersion` function of `ObjCAvailabilityCheckExpr` class.

This feels like a bug on the original change D22171. We cannot really call this function from a const object pointer because the function is not marked as const.

This diff adds the missing const specifier to fix the issue.
