Previously WinCheckAndInitializeNullTreatment() used elog() to emit an error message. ereport() should be used instead because it's a user-facing error. Also use existing get_func_name() to get a function's name, rather than own implementation. Moreover add an assertion to validate winobj parameter, just like other window function API.
