drm/xe: Fix memory leak in exec_queue_set_hang_replay_state()
The q->replay_state is blindly overwritten, which can potentially leak
memory that was previously allocated by vmemdup_user().
Return an error if q->replay_state is not empty.
Discovered using AI-assisted static analysis confirmed by Intel Product
Security.
