solve device issue in cos and sin in Qwen2's ROPE Embedding
Author: irislin1006
Pull request: yes

# What does this PR do?
This PR addresses a device mismatch issue in the `apply_rotary_pos_emb` function within the Qwen model implementation. Specifically, the cos and sin tensors, used for rope, were placed on the CPU, while other tensors (q, k, and position_ids) were on the GPU. This discrepancy caused a runtime error during training.

The fix ensures that cos and sin are moved to the same device as position_ids, resolving the inconsistency and allowing the model to run successfully on the GPU.
