cab7d1e4 - [mlir][reducer] Repalce module.emitWarning with module.emitError in ReductionTree pass (#190584)

[mlir][reducer] Repalce module.emitWarning with module.emitError in ReductionTree pass (#190584) This PR fixes the diagnostic message for mlir-reduce's reduction-tree pass when the input module is not "interesting". Previously, running with the warning pass would fail silently, and enabling debug options would only show a generic "pass manager run failed" message without any useful diagnostic information.
