[dynamo] fix disable_saved_tensors_hooks - graph break (#106875)
```python
def wrapper_fn(x):
with torch.autograd.graph.disable_saved_tensors_hooks("ERROR"):
y = x + 1
print("HI")
return y + 2
x = torch.randn(())
a = wrapper_fn(x)
opt = torch.compile(wrapper_fn, backend='eager', fullgraph=False)
e = opt(x)
```
Without the fix fails with,
```
Traceback (most recent call last):
