fft: Fix invalid shape error for complex-to-real transforms (#73012) Summary: Fixes https://github.com/pytorch/pytorch/issues/72910 `last_dim_size` is the expected output size for the Hermitian-compressed dimension and must be > 0. The confusingly named `ld` represents the input's last dim size which is calculated as `last_dim_size / 2 + 1` so could never be 0.
