test_fused_sdp_choice in test_transformers.py fix (#106587)
sdp dispatcher prioritizes flash attention over efficient attention: https://github.com/pytorch/pytorch/blob/main/aten/src/ATen/native/transformers/cuda/sdp_utils.cpp#L684-L687, and flash attention is enabled for sm75+: https://github.com/pytorch/pytorch/blob/main/aten/src/ATen/native/transformers/cuda/sdp_utils.cpp#L625. Thus, the unit test `test_fused_sdp_choice` from `test_transformers.py` which is failing on T4 (sm75) should have this `SM80OrLater` check changed to `SM75OrLater`: https://github.com/pytorch/pytorch/blob/main/test/test_transformers.py#L1914-L1917.
