updating nvfuser tests
Re-enabled the failing test `test_category_rule` since I don't have the repro;
removed `test_linear_1d_weight_mismatch_bias_dtype` since the old behavior is not supported in aten;
disabled `test_int_tensor_input` for pre-volta device since we have reduction `amax` in the test.
