[Bugfix] Fix the graph capture failure issue in the eagle3+full scenario. (#5553)

Browse Source 
### What this PR does / why we need it?
When launching the service in the scenario where the
cudagraph_mode is set to FULL and Eagle3 acceleration is enabled for
inference, an error in fia will cause graph capture to fail. This PR
fixes the issue.

### Does this PR introduce _any_ user-facing change?

### How was this patch tested?
