input: Make setting the same pointer cursor state again a no-op

Browse source 
If the client calls wl_pointer.set_cursor with the same surface and hot
spot coordinate that is already set, don't do anything as no state was
changed.

This avoids an issue where a client setting the same cursor surface
multiple times would receive wl_surface.leave/enter on that surface
every time.
