Subject: [PATCH] wayland: Destroy the seats before stopping the cursor surface
 event thread

Stopping the thread also destroys the queue used by pointer surfaces, and if any seats still have a surface associated with the queue at that time, it will cause a libwayland warning. Destroying the seats first ensures that all surfaces associated with the thread queue are destroyed before the queue is destroyed.
