### What this PR does / why we need it?
In reinforcement learning scenarios, weight updates are required, but
the current inference applies a transpose operation to the weights,
altering their shape. This causes a shape mismatch with the training
weights, triggering an error during weight updates.
### Does this PR introduce _any_ user-facing change?
### How was this patch tested?
- vLLM version: v0.10.1.1
