xulei 77ea873224 fix: resolve sync bug in DispathFFNCombine when expert num per card is 32 (#6416) ...

### What this PR does / why we need it?

Fix the synchronization deadlock issue in DispathFFNCombine module that
occurs on NPU cards when the number of experts per card exceeds 16 (the
bug manifests prominently when set to 32/128).

### Does this PR introduce _any_ user-facing change?
No, this is a bug fix for internal synchronization logic specific to NPU
expert dispatch, with no impact on external APIs, interfaces, or
end-user behaviors.
