gve: unlink old napi only if page pool exists

Browse Source 
Commit de70981f29 ("gve: unlink old napi when stopping a queue using
queue API") unlinks the old napi when stopping a queue. But this breaks
QPL mode of the driver which does not use page pool. Fix this by checking
that there's a page pool associated with the ring.
