Pull request: Remove redundant code from Qwen3VLProcessor

# What does this PR do?
As per title. 

There are two identical lines assigning `video_grid_thw = videos_inputs["video_grid_thw"]` in `Qwen3VLProcessor.__call__()`.  One of them can be safely removed for cleaner and more concise code.
<!--
