9e73e890 - [quant][core][gpu][improvement] Converted reinterpret_cast<T *>(some_int8_tensor.data_ptr()) calls to some_int8_tensor.data_ptr<int8_t> in quantized cudnn operator files (#75980)

[quant][core][gpu][improvement] Converted reinterpret_cast<T *>(some_int8_tensor.data_ptr()) calls to some_int8_tensor.data_ptr<int8_t> in quantized cudnn operator files (#75980) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/75980 Support for data_ptr<T> for quantized tensor was enabled in https://github.com/pytorch/pytorch/pull/75643. Rather than using reinterpret_cast, we can use this overload directly. The change is currently made in /aten/src/ATen/native/quantized/cudnn. (Note: this ignores all push blocking failures!) Test Plan: ``` python test/test_quantization.py -k test_qlinear_cudnn python test/test_quantization.py -k test_qconv2d_cudnn python test/test_quantization.py -k test_qadd_relu_cudnn ``` Reviewed By: jerryzh168 Differential Revision: D35720654 Pulled By: dzdang fbshipit-source-id: 5ba4b99f6cfaf1b482a0a3f5208c94e53cb05eba (cherry picked from commit 92e2480fa0862261bff42761d5eab8ee0bb3b075)
