[TensorPipe] Add guards against transferring GPU tensors (#40167) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/40167 In v1.6 TensorPipe will not support transferring GPU tensors so, just like other agents, it should raise the appropriate errors when the user attempts to do so. One such error is when sending the arguments, another is when sending the result. ghstack-source-id: 106059723 Test Plan: Re-enabled the test for this Differential Revision: D22091737 fbshipit-source-id: 23dda98bc006333c6179361e8cfaf00ecda06408
