d8d7af08 - Fix CUDA shared memory out of bound access in findPattern (#28989)

Fix CUDA shared memory out of bound access in findPattern (#28989) Summary: This fixes https://github.com/pytorch/pytorch/issues/28789 Only the first two elements of `smem` are used in this function but at the beginning, it resets all the `C10_WARP_SIZE` to 0. When the `scalar_t` is 64bit, it goes out of the total shared memory size which is `sizeof(int) * C10_WARP_SIZE`, although this does not lead to any failure in CI.
