When an error occurs while rewriting the parser tree for window functions
in the sqlite3WindowRewrite() routine, make sure that pParse->nErr is set,
and make sure that this shuts down any subsequent code generation that might
depend on the transformations that were implemented. This fixes a problem
discovered by the Yongheng and Rui fuzzer.
