drm/xe: Fix memory leak in exec_queue_set_hang_replay_state()
Description
In the Linux kernel, the following vulnerability has been resolved: 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. (cherry picked from commit f6b6cc1118bdbc4265fa8b3bdf8565b26f13e56e)
