[Inductor] [CPU] config.fallback_random = True has a negative effect for nn.Dropout1d, nn.Dropout2d, and nn.Dropout3d on CPU #142853
Description
🐛 Describe the bug
It's very strange if I want to ensure a stable output for RNG op (nn.Dropout1d, nn.Dropout2d, and nn.Dropout3d).
How to set config.fallback_random has the opposite effect on CPU and CUDA.
I guess there may be a place in the source code where the Boolean condition is written incorrectly.
Feel free to correct me if I am wrong (because maybe it was set that way on purpose?)
