Bug 10938 – ICE on recursive instantiation in opDispatch

And it had removed the necessity of the code in `DotTemplateInstanceExp::semanticY` for the issue 4003. Therefore, just remove the unnecessary code to fix the ICE. https://github.com/D-Programming-Language/dmd/commit/cd8a42547187ae9cb8ff3593efd3ee7a88697e72 Merge pull request #2840 from 9rnsr/fix10938 Issue 10938 - ICE on recursive instantiation in opDispatch
