Fix the coredump described by #106702 (#108002)
Fixes #106702 and add some tests
As shown by [maxUnpool1d](https://pytorch.org/docs/master/generated/torch.nn.MaxUnpool1d)(`MaxUnpool2d`, `MaxUnpool3d` also), `Input` and `Output` support `(N,C,*)` or `(C,*)`, but the c++ api currently supports the former, and the latter will cause a coredump.
