drm/qxl: use iterator instead of dma_resv_shared_list
I'm not sure why it is useful to know the number of fences in the reservation object, but we try to avoid exposing the dma_resv_shared_list() function. So use the iterator instead. If more information is desired we could use dma_resv_describe() as well.
