### What this PR does / why we need it?
This PR aims to fix setting of `speculative_config.enforce_eager` in
deepseek v3.2 mtp. The point is that, vllm sets
`speculative_config.enforce_eager` as True if using deepseek_v32 with
mtp. Since we support graph mode, we simply ignore it here. However,
this fix will also implicitly ignore user setting of
`speculative_config.enforce_eager`, we need to take care and remove it
once vllm supports this feature.
### Does this PR introduce _any_ user-facing change?
