          1. 🐛 Describe the bug

      Running `torch.nn.LPPool2d` with a stride value of an integer larger than the max int32 value causes the CUDA version to throw `RuntimeError: integer out of range`. But on CPU, no error is thrown. Please fix the inconsistency.

      Minimal reproduction:
      ```python
      import torch
      import numpy as np

      rng = np.random.default_rng(272)

      input_tensor = torch.tensor(rng.uniform(-1, 0, size=(1, 9, 1, 1)), dtype=torch.float64)
      norm_type = 2
      kernel_size = 1
      stride = np.iinfo(np.int32).max + 1
      ceil_mode = False

      output_cpu = torch.nn.LPPool2d(norm_type=norm_type, kernel_size=kernel_size, stride=stride, ceil_mode=ceil_mode)(input_tensor)

      1. No error
        output_gpu = torch.nn.LPPool2d(norm_type=norm_type, kernel_size=kernel_size, stride=stride, ceil_mode=ceil_mode).cuda()(input_tensor.cuda())
      2. RuntimeError: integer out of range
        ```
